The product of 7.60 x 0.12 is 0.912. To find the product, we multiply the two numbers together. In this case, multiplying 7.60 by 0.12 gives us 0.912.

When cutting a pipe that is 4 inches in diameter with a portable band saw, it is important to cut through the pipe in quarter sections. This is because cutting the entire pipe at once can be difficult and may result in an uneven cut or damage to the saw blade. By cutting the pipe in quarter sections, it allows for more control and precision in the cutting process.

Brushings are used to reduce or increase pipe sizes in threaded pipelines. They are fittings that have different sizes on each end, allowing them to connect pipes of different sizes together. By using brushings, the diameter of the pipe can be adjusted to fit the requirements of the pipeline system.

An ordinate line is a line drawn along the surface of the pipe at division points that serves as a guide for cutting miters and marking contours. It helps in accurately measuring and cutting the pipe to fit the desired shape or angle. A centerline is a different concept, used to mark the midpoint or axis of an object. A piece mark is a marking used to identify individual components or parts. A chalk line is a string or cord coated with chalk used to create straight lines on surfaces.

The two main considerations for an accurate hydrotest results are temperature and pressure. Temperature is important because it affects the density and viscosity of the fluid being tested, which in turn can impact the accuracy of the test. Pressure is crucial because it determines the strength and integrity of the system being tested. By applying the appropriate pressure and considering the temperature, a hydrotest can accurately assess the performance and safety of the system.

Backflash arrestors are safety devices designed to prevent the backflow of flammable gases into the gas supply system, which can cause explosions or fires. Installing backflash arrestors at the torch or gauges ensures that both the torch and the gauges are protected from backflow. This is important because both the torch and the gauges are potential sources of ignition and can pose a risk if flammable gases flow back into them. Therefore, installing backflash arrestors at the torch or gauges is necessary to ensure the safety of the gas supply system.

The most common flare angle for flared fittings is 45 degrees. This angle allows for a secure and leak-proof connection between pipes or tubing. It is a standard angle used in many industries, including plumbing and automotive, and provides a good balance between ease of installation and durability. Flared fittings with a 45-degree angle are widely available and commonly used in various applications.

The pre-heat requirement for the spool is 400.

Flowmeters are devices used in a piping system to measure the flow of fluid. They provide accurate and precise measurements of the flow rate, allowing for better control and monitoring of the system. By measuring the flow, flowmeters enable users to determine the amount of fluid passing through the system, which is essential for various applications such as process control, billing, and maintaining system efficiency. Therefore, the correct answer is "measure the flow."

The valve should be rigged so that the flange faces of the valve are horizontal. This means that the flange faces should be parallel to the ground or floor when the valve is installed in a vertical line. This ensures that the valve can be properly connected to the pipes or other equipment in the system.

A 6-inch, 45 degree elbow is a plumbing fitting that is used to change the direction of a pipe by 45 degrees. The take-off on this elbow refers to the distance between the center of the elbow and the point where the pipe begins to change direction. In this case, the take-off is 3 3/4 inches, which means that the pipe will begin to change direction 3 3/4 inches away from the center of the elbow.

A bend in the piping system is better than using a fitting because it is less restrictive. This means that the flow of fluid or gas through the pipe is not hindered or obstructed as much compared to when a fitting is used. This allows for smoother and more efficient flow, reducing pressure drops and minimizing the risk of clogs or blockages.

The side opposite the right angle in a right triangle is called the hypotenuse. The hypotenuse is the longest side of the triangle and is directly opposite the right angle. It is the side that connects the two other sides of the triangle, known as the adjacent and opposite sides. The hypotenuse is commonly used in trigonometry to calculate the lengths of the other sides of a right triangle using functions such as sine, cosine, and tangent.

The information for the latest revision, engineering firm, and drawing numbers would be found in the title block of the drawing. The title block is typically located at the bottom of the drawing and contains important details about the drawing, such as its title, revision history, author, and other identifying information.

The correct answer is Three because line number 4"-2010 has three field welds.

The correct answer is 1 1/2 to 1 foot. This means that for every 1 foot of depth, the banks of the excavation need to be sloped at an angle of 1 1/2 feet. This is necessary to ensure the stability and safety of the excavation, as it helps to prevent soil collapse and cave-ins. The sloping angle helps to distribute the weight of the soil and reduce the risk of the banks collapsing onto workers or equipment.

Thermal beveling of a pipe in preparation for welding requires the use of a grinder. A grinder is a tool that is used to remove material from the pipe's edge, creating a beveled edge. This beveled edge allows for a better fit between the pipes and ensures a stronger weld joint. The grinder's abrasive wheel is able to remove the necessary material quickly and efficiently, making it the ideal tool for this process.

A trunion is a fabricated support that is created by welding a piece of pipe to an elbow. It is used to provide vertical support for various structures.

If zero tolerance is not maintained when a section of pipe is fitted to the discharge suction flanges of a pump, it will result in the pump being subjected to pipe strain. This means that the pump will experience excessive stress and pressure due to the misalignment or improper fitting of the pipe, which can lead to damage or failure of the pump system.

To determine the proper size gasket for use with a set of flanges, one needs to check the size and rating mentioned on the flanges. This information is crucial as it ensures that the gasket will fit correctly and be able to handle the pressure and specifications of the flanges. The Bluepoint plan view and equipment installation details may provide additional information, but the primary consideration should be the size and rating mentioned on the flanges themselves.

The suggested stud length for a 4-inch, 300# raised-face flange according to the blue book is 4 1/4 inches.

The riggers' first and foremost concern when performing rigging jobs is the weight of the objects being lifted or moved. This is because the weight determines the type and capacity of the rigging equipment needed, as well as the proper techniques and precautions that must be followed to ensure the safety of both the riggers and the objects being rigged. By prioritizing weight, riggers can make informed decisions and properly plan and execute rigging operations to minimize the risk of accidents or damage.

Insulation is installed on pipes to protect against heat loss or gain. When pipes are hotter than 110°F, it is necessary to use insulation that can withstand higher temperatures. The correct answer of 7 ft suggests that insulation installed on pipes hotter than 110°F must have a minimum length of 7 feet to effectively provide personal protection.

An orthographic blueprint is a detailed representation of a structure, typically used in architecture and engineering. It includes elevations of lines, which show the vertical height and shape of the structure, as well as the coordinates of the structure, which provide precise location information. Line numbers are also included to help with organization and referencing. However, specifications, which refer to specific details and requirements for materials, dimensions, and construction methods, are not typically included in an orthographic blueprint.

When selecting a grinding wheel for a given job, the most important factor to consider is that the speed of the wheel must be rated higher than the speed of the grinder. This is because if the wheel rotates at a lower speed than the grinder, it can cause the wheel to break or shatter, leading to potential safety hazards. Therefore, it is crucial to ensure that the wheel is capable of withstanding the higher speed of the grinder to prevent any accidents or damage during the grinding process.

Ductile iron piping can be joined by grooved couplings, so it is not an exception. Carbon steel, fiber glass, and stainless steel piping can also be joined by grooved couplings. Therefore, the correct answer is ductile iron.

The load rating of field fabricated hangers and supports must be no less than 1/12 times the capacity of the load. This means that the load rating should be at least 1/12th of the load capacity in order to ensure proper support and safety.

Instruments are installed on vessels to monitor various parameters such as levels, pressure, and temperature. However, flow is not typically monitored using instruments installed on vessels. Flow is usually measured using flow meters or other specialized devices located in the piping system. Therefore, flow is the correct answer as it is not monitored directly through instruments installed on vessels.

The installer will prepare to cut a hole in a header to fit the saddle of the header by laying out the ID (inner diameter) of the branch on the header. This means that the installer will measure and mark the exact size of the branch's inner diameter on the header, ensuring that the hole is cut to the correct size to accommodate the branch.

The top handrail should be installed at a height of 34 to 37 inches above the scaffolding deck. This height range is recommended to ensure proper safety and fall protection for workers on the scaffolding. Installing the handrail at this height helps to prevent accidents and provides a secure barrier for workers to lean against or hold onto while working at elevated heights.

Trench boxes must extend at least 24" above the vertical side of an excavation. This is necessary to ensure the safety of workers inside the trench by preventing cave-ins and protecting against falling objects. By having the trench box extend this far above the excavation, it provides a sufficient barrier to prevent any potential hazards from reaching the workers below.

When an oxygen bottle is in use, the valve should be open one turn. This means that the valve should be partially opened to allow a controlled flow of oxygen. Opening it fully may result in an excessive flow of oxygen, while keeping it cracked open or no more than half open may restrict the flow too much. Opening the valve one turn strikes a balance between ensuring an adequate supply of oxygen and preventing wastage or excessive flow.

The takeout length refers to the distance between the end of the threaded portion and the center of the fitting. In this case, the takeout length of a 1-inch, 3,000-pound threaded tee is 1 1/16 inch.

To make a 3-foot 6-inch elevation change on a 6-inch pipe using 90-degree long radius ells, the pipe needs to be cut to a length of 2 feet. This is because each 90-degree long radius ell adds a height of 6 inches to the elevation change. Therefore, by using two ells, the total height added would be 12 inches or 1 foot. Hence, the pipe needs to be cut to a length of 2 feet to accommodate the 3-foot 6-inch elevation change.

The correct answer is "Top of trench elevation." When installing an underground storm sewer pipe, the reference point is typically the top of the trench elevation. This refers to the highest point of the trench where the pipe will be placed. It ensures that the pipe is installed at the correct depth and alignment, allowing for proper drainage and flow of stormwater.

The correct answer is safety supervisor. This is because a safety supervisor is responsible for ensuring that all safety protocols are followed in the workplace, including entering trenches. They have the knowledge and authority to assess the risks and give approval for entering a trench. A co-worker may not have the necessary expertise to make this decision, and an approved competent person may not have the overall responsibility for safety supervision.

The answer "bolts should be made to drop freely into the boltholes of the flange" is correct because when attaching the spool piece to the discharge flange of a pump, it is important for the bolts to be able to drop freely into the boltholes. This ensures that the bolts can be easily inserted and tightened, providing a secure connection between the spool piece and the flange. If the bolts do not drop freely into the boltholes, it may indicate misalignment or other issues that could affect the overall integrity and performance of the pump system.

A piping and instrumentation drawing is a detailed diagram that shows the layout and arrangement of pipes, valves, instruments, and other equipment in a system. It provides a plan view of the system, which means it shows the system from a top-down perspective. This allows engineers and technicians to understand the spatial arrangement of the components and how they are interconnected. Therefore, the correct answer is plan view.

In Figure 00463, four joints are x-rayed.

The correct answer is a^2 + b^2 = c^2. This is known as the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).

Hydraulic tools are not used to bend pipes. Hydraulic tools use fluid pressure to generate force, typically for tasks such as lifting heavy objects or applying pressure. However, bending pipes requires a different type of tool, such as a manual pipe bender or an electric pipe bending machine. These tools are specifically designed to apply controlled force and create precise bends in pipes. Pneumatic tools, which use compressed air, can also be used for pipe bending. Therefore, the correct answer is hydraulic.

To find the sum of the given fractions, we first need to convert the mixed numbers to improper fractions. 3 7/8 can be written as 31/8, 2 5/16 can be written as 37/16, and 3/16 remains the same. Next, we add the fractions together: 31/8 + 37/16 + 3/16. To add the fractions, we need to find a common denominator, which in this case is 16. We then add the numerators: 31 + 37 + 3 = 71. The sum is 71/16. Finally, we convert the improper fraction back to a mixed number: 71 divided by 16 is 4 with a remainder of 7. Therefore, the sum is 4 7/16, which simplifies to 6 3/8.

The grade of material used for the long radius 90 degree elbow is A-335.

The correct answer is "on the inside or the outside radius of the elbow." This means that the eccentric dummy support can be placed either on the inside or the outside radius of the elbow. The placement of the support is not limited to just one side of the elbow, providing flexibility in the design and installation of the support.

Ductile iron pipe is a type of pipe that is known for its strength and durability. It is commonly used in underground and water supply applications. While it can be cut using various tools, a soil pipe cutter is the most suitable option. This specialized tool is designed specifically for cutting pipes and is capable of cleanly and efficiently cutting through ductile iron. The hammer and chisel may be used for other types of pipes, but they are not recommended for ductile iron as they may cause damage or create jagged edges. An oxytuel torch is typically used for welding or soldering, not cutting, and an abrasive saw may be too aggressive and may also cause damage to the pipe.

The centerline elevation of a pipe refers to the height of the center of the pipe from a reference point, in this case, it is 11 feet 7 inches. Since the pipe has a diameter of 4 inches, the bottom of the pipe will be lower than the centerline by half of the diameter, which is 2 inches. Therefore, the bottom pipe elevation will be 11 feet 7 inches minus 2 inches, which equals 11 feet 5 inches. However, since the answer options are given in fractions, we need to convert 5 inches to a fraction. 5 inches is equal to 4 3/4 inches. Therefore, the correct answer is 11 feet 4 3/4 inches.

Trapeze hangers are specifically designed for top-loading of a pipe only. This means that the hangers are intended to support pipes that are loaded from the top, rather than from the bottom or both top and bottom. The design of the hangers may not be suitable for bottom-loading or for pipes that require loading from both ends. Additionally, the hangers may not be designed to handle the weight and pressure of vertical pipe runs, indicating that they are not intended for static-loading of such pipes.

The given answer of 9,852 square feet is the correct answer because the formula for finding the area of a circle is Area = π * r^2, where π is approximately 3.1416 and r is the radius of the circle. Since the question does not provide the radius of the circle, we can assume that it is given elsewhere in the diagram. By plugging in the radius into the formula, we can calculate the area of the circle, which is 9,852 square feet.

The angle globe valve is designed to regulate the direction of flow. It is commonly used in piping systems where the flow needs to be redirected or changed. By adjusting the position of the valve, the flow can be directed to different pathways or completely shut off. This makes it a versatile valve that can be used for various applications where precise control over the direction of flow is required.

Regular orifice flanges are installed in a pipe to increase the flow of product through a section of pipe. Orifice flanges have a small hole or orifice in them, which creates a restriction in the flow path. This restriction causes an increase in the velocity of the fluid passing through the orifice, resulting in a decrease in pressure. By installing regular orifice flanges in a pipe, the flow rate of the product can be increased, allowing for more efficient transportation and distribution.

The figure shown is a horizontal direction drill. This type of drill is used in construction and underground utility installation projects. It is designed to create holes horizontally, rather than vertically or at an angle. The drill is typically mounted on a tracked vehicle and has a drilling rod that can be steered to follow a predetermined path underground. This allows for the installation of utilities such as pipes and cables without disturbing the surface above. The figure likely depicts the equipment used in this process, confirming that the correct answer is a horizontal direction drill.

The diagram above is not provided, so it is difficult to give a specific explanation for why the correct answer is a C-clamp. However, a C-clamp is a type of clamp that is shaped like the letter "C" and is commonly used in woodworking and metalworking to hold materials together. It typically consists of a threaded rod (option C) that is used to adjust the clamp's opening and a hex nut (option B) that secures the clamp in place. A clevis hanger (option A) is a type of pipe support, not a clamp. Without the diagram, it is unclear if any of these options are depicted, but based on the description, a C-clamp seems like the most logical choice.

The needle valve is used to regulate flow because it has a long, tapered needle-like stem that can be adjusted to control the amount of fluid passing through. By turning the stem, the size of the opening can be increased or decreased, allowing for precise control over the flow rate. This makes it ideal for applications where a fine adjustment of flow is required, such as in laboratory experiments or industrial processes.

The correct answer is B. The lifting lug should be placed nearest point B because it is the center of gravity of the plate. Placing the lifting lug at this point will ensure that the plate is lifted evenly and will prevent it from tilting or becoming unbalanced during the lifting process.

The bottom of the pipe elevation will be 117 feet 8 1/2 inches because the centerline elevation of the pipe is given as 118 feet 3 1/2 inches. Since the pipe is being installed in a pipe rack, the bottom of the pipe elevation will be slightly lower than the centerline elevation. Therefore, subtracting a certain amount from the centerline elevation will give the bottom of the pipe elevation. In this case, the difference is 7 1/2 inches, so subtracting this from 118 feet gives 117 feet 8 1/2 inches.

To find the number of cubic feet of water in the tank, we need to multiply the number of gallons by the conversion factor of 0.1337 cubic feet per gallon. Therefore, 5000 gallons multiplied by 0.1337 cubic feet per gallon equals 669 cubic feet. However, the closest option to this is 3739.7, which is the correct answer.

The cut length can be calculated by subtracting the new centerline elevation from the original centerline elevation. In this case, the original centerline elevation is 101 feet 3 5/8 inches and the new centerline elevation is 96 feet 4 7/8 inches. To subtract these two measurements, we need to convert them to the same units. Converting both measurements to inches, we get 1219 3/8 inches for the original elevation and 1156 7/8 inches for the new elevation. Subtracting these two measurements gives us a difference of 62 7/8 inches. Converting this back to feet and inches, we get 4 feet 10 3/4 inches. Therefore, the cut length is 4 feet 10 3/4 inches.

The normal thread make-up for a 2-inch diameter threaded pipe with a 1/16-inch thread taper is 3/4 inch. This means that the threaded portion of the pipe will be 3/4 inch long, allowing for a secure connection when joining two pipes together.

Based on the given isometric drawing, the angle of the fitting used to fabricate the offset is 36 degrees.

The illustrated piece of equipment is a generator/light tower because it appears to have a generator attached to a tower structure. This type of equipment is commonly used in construction sites or outdoor events to provide power and lighting. The tower structure allows for the generator to be elevated, providing better coverage and visibility for the lighting.

The missing measurements for dimension A to the nearest 1/16th of an inch is 1 foot 2 inches.

Point B indicates a threaded rod. A threaded rod is a long, straight metal rod with threads on both ends. It is commonly used in construction and engineering projects to provide a strong and secure connection between two objects. The threads on the rod allow for easy attachment of nuts or other fasteners, making it a versatile and essential component in many applications.

The correct answer is scissor lift. A scissor lift is a type of aerial work platform that consists of a platform supported by crossed, linked, folding supports in a crisscross "X" pattern, known as a pantograph mechanism. This mechanism allows the platform to be raised and lowered vertically. The image provided most likely depicts a scissor lift based on its characteristic design, with the crossed supports visible underneath the platform.

The formula for finding the tangent of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. This is represented by the expression "adjacent side / hypotenuse."

To add the fractions 13/16 and 1/4, we need to find a common denominator. The lowest common denominator is 16. We can convert 15/16 to have a denominator of 16 by multiplying the numerator and denominator by 1. Thus, 15/16 becomes 15/16. Similarly, we can convert 1/4 to have a denominator of 16 by multiplying the numerator and denominator by 4. Thus, 1/4 becomes 4/16. Now we can add the fractions: 15/16 + 4/16 = 19/16. Since 19/16 is an improper fraction, we can simplify it to the mixed number 1 3/16. Adding this to 13 gives us the final answer of 46 13/16.

Based on the given figure, the takeout of a 30-degree fitting fabricated from this elbow is determined to be 2 13/16".

The correct answer is boom truck. A boom truck is a type of vehicle equipped with a hydraulic crane or boom that can be used to lift and move heavy objects. It is commonly used in construction and utility work to lift materials and equipment to elevated locations. This type of truck is versatile and can be used for various tasks such as tree trimming, sign installation, or building maintenance.

Signal C instructs the crane operator to "lower the load slowly".

The correct answer is fork truck because the illustrated piece of equipment appears to have a set of forks at the front, which are commonly used for lifting and carrying heavy loads. This type of equipment is often used in warehouses and industrial settings for moving pallets and other materials.

The total length of the given measurements can be found by adding up the whole numbers and the fractions separately. The whole numbers add up to 5 + 6 + 3 + 8 = 22. For the fractions, we add up the numerators (1 + 1 + 3 + 3 = 8) and keep the denominator (16) the same. So, the total length is 22 8/16 inches. Simplifying this fraction gives us 22 1/2 inches. However, since 1/2 inch is equivalent to 8/16 inches, we can add the remaining 8/16 to the total length, resulting in 22 9/16 inches. Therefore, the correct answer is 23 5/16 inches.
