The wire size is determined by the American Wire Gauge (AWG) system, where a smaller gauge number represents a larger wire size. Therefore, the 14 AWG wire is bigger than the 18 AWG wire.

Oxygen leaking into the system can cause various issues with the engine. When there is an oxygen leak, the engine may be unable to start because the proper air-fuel mixture is disrupted. Additionally, the engine may miss or hesitate during operation due to the incorrect ratio of oxygen to fuel. Furthermore, the engine may not be able to pull a load or reach full speed because the presence of excess oxygen affects its performance. Therefore, all the given options - engine unable to start, engine misses/hesitates, and unable to pull load and come to full speed - can be caused by oxygen leaking into the system.

The correct answer is "Intake, compression, combustion, exhaust." In a four-stroke engine, the intake stroke involves the intake valve opening and the piston moving downward to allow air and fuel to enter the cylinder. The compression stroke occurs when the intake and exhaust valves are closed, and the piston moves upward, compressing the air and fuel mixture. The combustion stroke happens when the spark plug ignites the compressed mixture, causing an explosion that forces the piston back down. Finally, the exhaust stroke takes place when the exhaust valve opens, and the piston moves back up, pushing the burned gases out of the cylinder.

A screw compressor operates by compressing air or gas, which generates heat. If the discharge temperature is too low, it can cause condensation to form within the compressor. This condensation can mix with the lubricating oil and other contaminants, leading to corrosion, reduced efficiency, and potential damage to the compressor components. Therefore, it is important to maintain a discharge temperature that is high enough to prevent condensation from forming. 140 degrees Fahrenheit is considered cool enough to allow harmful condensation to form, making it an incorrect choice for keeping a screw compressor operating.

The primary function of a scavenge line on a screw compressor package is to return the oil into the suction if it gets through the coalescent filter. This is important because the oil can potentially contaminate the suction side of the compressor, leading to reduced efficiency and potential damage to the compressor components. By returning the oil back into the suction, the scavenge line helps to maintain the proper oil circulation and prevent any adverse effects on the compressor operation.

Gas aftercoolers are typically the most affected component when corrosive gas is present because cooling the gas after compression allows water to condense. When this condensed water mixes with corrosive gases like CO2 or H2S, it forms acid. This acid can corrode the components of the aftercooler, causing damage and degradation over time. Therefore, the presence of corrosive gases combined with the condensation of water makes the gas aftercoolers more susceptible to damage.

The correct firing order for a GM 5.7L V8 engine is 18436572. This firing order specifies the sequence in which the engine's cylinders ignite and produce power. Each number represents a cylinder, and the order indicates the order in which they fire. This specific firing order ensures smooth and efficient engine operation, as it is designed to minimize vibrations and maximize power output.

The oil in an oil-flooded rotary screw compressor serves multiple functions. Firstly, it lubricates the bearings, ensuring smooth operation and reducing friction between moving parts. Secondly, it seals the rotors to each other and the housing, preventing any leakage and maintaining the efficiency of the compressor. Lastly, it dissipates the heat generated during compression, preventing overheating and potential damage to the compressor. Therefore, the correct answer is "All of the above."

To verify if the coalescent filter needs to be changed, one should check the differential pressure across the discharge filter. If the pressure difference is high, it indicates that the filter is clogged and needs to be replaced. This is because a clogged filter restricts the flow of oil, causing an increase in pressure. By monitoring the differential pressure, one can determine the condition of the filter and take necessary action to maintain the efficiency of the system.

To change the direction of rotation on a 3 phase electric motor, you need to switch two legs of power. By swapping the connections of two of the three power supply wires, the motor's magnetic field will be reversed, causing it to rotate in the opposite direction. This is a common method used to change the rotation direction of a 3 phase electric motor.

A plunger lift is a device used to remove fluids from a gas well. It is designed to enhance the production of natural gas by periodically lifting and removing accumulated liquids from the wellbore. This helps to maintain optimal gas flow and prevent the buildup of liquids that can hinder the production process. The plunger lift system is commonly used in gas wells to improve efficiency and maximize the extraction of natural gas.

The "horse shoe" symbol on a multi-meter represents the Ohms function, which is used for checking continuity and measuring resistance. This function allows the user to determine whether there is a complete electrical connection between two points and to measure the resistance of a component or circuit.

When a compressor is applied to a well with a plunger lift, well cycle times should be adjusted. This is because the compressor helps to increase the production rate of the well by providing additional pressure to lift the plunger. Adjusting the cycle times ensures that the plunger is lifted and dropped at the optimal intervals to maximize production efficiency. Therefore, the statement "well cycle times should not be adjusted" is incorrect.

Ignition wires carry the electrical current from the distributor to the spark plugs, providing the necessary spark for combustion in the engine. Over time, these wires can become worn or damaged, leading to a weak or inconsistent spark. This can cause stress on the distributor cap and rotor, as they are responsible for distributing the spark to the correct spark plug. If the ignition wires are faulty, it can result in misfires, engine performance issues, and ultimately, distributor cap and rotor failures. Therefore, the statement that ignition wires can cause distributor cap and rotor failures is true.

The typical pneumatic dump system requires a pilot pressure of 20-30 psig. This pressure is necessary to activate the system and release the compressed air. The range of 20-30 psig ensures that there is enough pressure to effectively operate the system without exceeding the maximum pressure limit.

If the tank pressure exceeds the relief hatch pressure, the tanks will vent gas. This is important in a vapor recovery application because it helps prevent the over pressurization of the tank, which can lead to safety hazards such as explosions. By keeping the tank pressure below 8 ounces, the risk of over pressurization and potential gas venting is minimized, ensuring the safe operation of the vapor recovery system.

The correct answer is that the compressor is marked with the correct rotation and the motor must turn accordingly. This means that there should be a label or marking on the compressor indicating the direction in which it should rotate. The motor should then be installed in such a way that it rotates in the same direction as indicated by the compressor. This ensures that the motor is rotating in the correct direction.

The larger the diameter of a pipe, the greater its capacity to flow. In this case, the 6" I.D. pipe has a larger diameter than the two 4" I.D. pipes. Therefore, the 6" I.D. pipe can flow more than the two 4" I.D. pipes.

Natural gas that has a specific gravity (S.G.) of 0.65 is lighter than air. Specific gravity is a measure of the density of a substance compared to the density of another substance, usually water. Since the specific gravity of natural gas is less than 1, it means that it is less dense than air. Therefore, natural gas will tend to rise and disperse in the atmosphere rather than sink, making it lighter than air.

If the fuel pot is operated at 60 psig, it can result in difficulty starting, damaged pneumatic valves, and a busted diaphragm on the ounce regulator. Operating the pot at this pressure can cause issues with the fuel system, leading to these potential problems.

The correct firing order for a typical in-line six cylinder engine is 153624. This means that the cylinders fire in the order of 1, 5, 3, 6, 2, and 4. The firing order is important because it determines the sequence in which the spark plugs ignite the fuel mixture in each cylinder. This specific firing order is commonly used in in-line six cylinder engines to ensure smooth and efficient combustion.

When the voltage goes up for a constant load, the current decreases. This is because according to Ohm's Law, the current is inversely proportional to the voltage. Therefore, as the voltage increases, the resistance of the load remains constant, causing the current to decrease.

The correct answer is 2500. MSCFD stands for "thousand standard cubic feet per day." Therefore, "2.5 million per day" can be converted to 2,500 MSCFD by dividing 2.5 million by 1000.

A rotary screw machine is the best fit for this application because it is capable of handling a wide range of pressure differentials. In this case, the pressure differential is 295 psig, which falls within the capabilities of a rotary screw machine. Additionally, rotary screw machines are known for their efficiency and reliability, making them a suitable choice for various applications.

When two 12 volt batteries are wired in parallel, they provide 12 volts. When batteries are wired in parallel, the positive terminals are connected to each other and the negative terminals are connected to each other. This configuration allows the batteries to share the load and effectively act as a single battery with the same voltage. Therefore, the voltage remains the same, which in this case is 12 volts.

PSIA stands for "pounds per square inch absolute," while PSIG stands for "pounds per square inch gauge." The term "absolute" in PSIA refers to the measurement of pressure relative to a perfect vacuum, while "gauge" in PSIG refers to the measurement of pressure relative to atmospheric pressure. Since atmospheric pressure is always positive, PSIA will always have a higher number compared to PSIG, which can have both positive and negative values.

The question asks for the equivalent measurement in inches of mercury vacuum for -3 psig, which means 3 psi below atmospheric pressure. The correct answer is 6" hg vac because -3 psig is equal to 6 inches of mercury vacuum.

A check valve on the inlet of a screw compressor is critical because it prevents various issues during shutdown and autostart. Without a check valve, high pressure can flow back to the package inlet, which can cause damage as the inlet is not designed to handle such pressure. Additionally, without a check valve, oil can flow back to the scrubber and be lost through the autodump, leading to oil loss. Furthermore, if pressure leaks back to suction during an autostart, it can trigger an unintentional start attempt. Therefore, having a check valve on the inlet of a screw compressor is crucial to avoid these potential problems.

To test for proper function of the typical magnetic pick-up used in the equipment, it is necessary to check for at least 2 volts AC. This is because the magnetic pick-up generates an alternating current (AC) signal as it senses the magnetic field. By checking for at least 2 volts AC, we can ensure that the pick-up is functioning correctly and producing the expected signal.

When a natural gas engine is "leaned out," it means that the air-fuel mixture is adjusted to have less fuel and more air. This adjustment leads to a decrease in the amount of fuel being burned, resulting in a lower combustion temperature. As a direct consequence, the exhaust temperature decreases. Therefore, the correct answer is "It goes down."

Compressing 0.65 S.G. methane gas will create LESS heat from compression than air will. This is because methane gas has a lower specific heat capacity compared to air, meaning it requires less energy to raise its temperature. Therefore, compressing methane gas will generate less heat compared to compressing air under the same operating conditions.

The correct answer is "All of the above". This means that all of the options mentioned - weak battery, highly loaded compressor, and short circuit in the starting system - can be common reasons for an engine starter fuse to blow. A weak battery may not provide enough power to start the engine, causing the fuse to blow. A highly loaded compressor can put excessive strain on the starter, leading to a blown fuse. Additionally, a short circuit in the starting system can cause an overload and result in the fuse blowing.

If the Vi ratio of a screw compressor is too low for an application, it means that the volume index (Vi) is not optimal for the specific requirements. This can lead to excessive horsepower consumption, as the compressor will need to work harder to compress the air or gas. A low Vi ratio indicates that the compressor is not efficiently compressing the fluid, resulting in higher energy consumption. Therefore, excessive horsepower consumption is the likely outcome when the Vi ratio is too low.

A lean burn engine operates with an excess of oxygen in the exhaust to ensure efficient combustion. Having about 6.5% excess oxygen allows for complete combustion of fuel, resulting in lower emissions and improved fuel efficiency. This level of excess oxygen is considered optimal for lean burn engines.

Keeping the tank pressure no less than 2 ounces is important in a vapor recovery application to prevent the induction of air. If the tank pressure drops below this level, it can create a vacuum which can lead to air being drawn into the system. This can cause contamination and affect the efficiency of the oil transfer process. Additionally, maintaining the correct flow rate is also important in a vapor recovery application to ensure optimal performance. Therefore, the correct answer is to keep from inducing air.

A typical firing voltage for a spark plug in good condition is 12,000 volts. This high voltage is necessary to create a spark that can ignite the air-fuel mixture in the engine cylinder. The spark plug acts as a bridge between the electrical system and the combustion chamber, and the high voltage helps to ensure a strong and consistent spark for efficient combustion.

An engine running too hot can be caused by various factors such as low timing advance, a soft water pump suction hose, or loose cooling fan belts. However, a fuel mixture that is too lean is not a probable cause of the problem. A lean fuel mixture means that there is a higher proportion of air to fuel, which typically results in a cooler combustion temperature. Therefore, a lean fuel mixture would not cause the engine to run too hot.

ANSI 150 series flanges are not typically referred to as "150-pound" flanges. While they can handle higher pressure without leaking, they are actually rated for 300 psig, not 150 psig. Therefore, the given statement is false.

As an engine's load increases, more air is required for combustion. This leads to an increase in the intake manifold pressure, as the engine needs to draw in more air to meet the increased demand. Therefore, the correct answer is "Pressure increases."

When the discharge pressure goes up, the coalescent filter will work better because higher pressure helps in the coalescing process. The increased pressure forces the particles and contaminants to come together and form larger droplets, making it easier for the filter to capture and remove them. This leads to improved filtration efficiency and better performance of the coalescent filter.

Based on the given application specifications, a rotary screw machine would be the best fit. This is because a rotary screw compressor is capable of handling both vacuum and pressure applications, making it suitable for the specified PS (14" hg vac) and PD (25 psig). Additionally, rotary screw compressors are known for their efficiency and reliability, making them a popular choice for various industrial applications.

An MSCFD is an abbreviation for "One thousand standard cubic feet per day." This unit of measurement is commonly used in the oil and gas industry to quantify the flow rate of natural gas. It represents the volume of gas that is produced or consumed per day at standard temperature and pressure conditions.

If the seal oil in a liquid ring gets contaminated with condensate, it will not cause any serious problems. This suggests that the contamination does not affect the functioning of the liquid ring or its components. It is possible that the contamination may have minimal or no impact on the overall performance or efficiency of the liquid ring system.

A compressor is making a ratio between the suction pressure and the discharge pressure. In this case, the suction pressure is given as 14" hg vac (vacuum) and the discharge pressure is given as 188 PSIG (pounds per square inch gauge). To calculate the ratio, we need to convert the suction pressure from vacuum to PSIG. Since 1 PSIG is equivalent to 2.036" hg vac, the suction pressure can be converted to -28.504 PSIG. Now we can calculate the ratio by dividing the discharge pressure by the suction pressure: 188 PSIG / -28.504 PSIG = -6.58. However, the absolute value of this ratio is taken, resulting in 6.58. Therefore, the correct answer is 26.08.

A 4-20 mA pressure transducer is classified as an analog end device because it produces a continuous and varying output signal (4-20 mA) that corresponds to the measured pressure. Analog devices provide a smooth and continuous representation of the measured variable, in this case, pressure, allowing for precise and accurate measurements. Pneumatic end devices use compressed air as the input/output medium, while digital end devices use digital signals for communication. However, a 4-20 mA pressure transducer operates on an analog signal, making it an analog end device.

Both options B and D suggest signs or symptoms of a contaminated and "plugged off" coalescent filter. Option B, compressor oil loss, indicates that the filter is not effectively removing contaminants from the system, leading to oil loss. Option D, increased back pressure, suggests that the filter is becoming clogged and obstructing the flow of air, resulting in higher pressure in the system. Therefore, both options B and D indicate that the coalescent filter may be contaminated and "plugged off."

Forcing more oil into a screw compressor will usually increase gas flow because the oil acts as a lubricant and helps to seal the gaps between the screw rotors, reducing internal leakage and improving the compression process. This allows for more efficient compression and increased gas flow.

The A-300 liquid ring is capable of achieving more compression ratios without damage compared to the other options listed. This is because the liquid ring compressor operates by using a liquid ring to compress the gas, which allows for higher compression ratios without causing damage to the system. In contrast, a 2 stage reciprocating compressor and a plunger lift may have limitations in terms of compression ratios and potential for damage. A hair dryer, on the other hand, is not designed for compression and therefore is not capable of achieving high compression ratios.

A Murphy L1200 liquid level switch is classified as a digital end device because it uses digital technology to detect and measure the level of liquid. Unlike pneumatic end devices that rely on air pressure or analog end devices that use continuous signals, the Murphy L1200 switch operates using discrete digital signals to indicate whether the liquid level is above or below a certain threshold. This makes it more precise and accurate in its measurements, making it suitable for various industrial applications where precise liquid level monitoring is required.

A red blood cell is about 6-8 microns in diameter, which is larger than the 5-micron rating of the compressor inlet filters and the 11-micron rating of the compressor oil filters. Therefore, a red blood cell is about the size that the filters are designed to catch.
