    What is the minimum setting depth for a 45 foot pole in clay?

    • 5.5 feet

    • 6.0 feet

    • 6.5 feet

    • 7.0 feet

    Correct Answer
    A. 6.5 feet
    Explanation
    The minimum setting depth for a 45-foot pole in clay is 6.5 feet. This depth is necessary to ensure stability and prevent the pole from leaning or falling over. Clay soil has a tendency to expand and contract with moisture changes, so a deeper setting depth is required to provide sufficient support and prevent the pole from being affected by these soil movements.

    What is the preferred method of polyethylene encasement for Ductile Iron Pipe?

    • Method A

    • Method B

    • Method C

    • Method D

    Correct Answer
    A. Method A
    Explanation
    The preferred method of polyethylene encasement for Ductile Iron Pipe is Method A. This method is considered the most effective and widely used technique for protecting the pipe from corrosion and extending its lifespan. It involves wrapping the pipe with a layer of polyethylene material, which acts as a barrier against moisture and other corrosive elements. Method A has been proven to provide excellent protection and durability, making it the preferred choice in the industry.

    When sagging conductors, the tension in the bottom conductors should be about ___% less than the top conductors.

    • 3 %

    • 5 %

    • 7 %

    • 9 %

    Correct Answer
    A. 3 %
    Explanation
    When sagging conductors, the tension in the bottom conductors should be about 3% less than the top conductors. This is because when conductors sag, the bottom conductors experience more tension due to the weight of the sagging conductors above them. By reducing the tension in the bottom conductors by 3%, it helps to balance the tension distribution and prevent excessive strain on the conductors.

    The capacity of the circulation system for a swimming pool shall be sufficient to disinfect the entire volume of the pool water _______ times in 24 hours.

    • 2

    • 4

    • 6

    • 12

    Correct Answer
    A. 4
    Explanation
    The capacity of the circulation system for a swimming pool should be sufficient to disinfect the entire volume of the pool water four times in 24 hours. This ensures that the water is constantly being treated and kept clean. If the circulation system is not able to achieve this level of disinfection, there is a risk of bacteria and other contaminants building up in the pool water, which can be harmful to swimmers. Therefore, it is important to have a circulation system that can adequately handle the volume of the pool and maintain proper disinfection.

    During a continuity test for fuel dispensers, the resistance reading between the nozzle spout and the dispenser fuel-outlet fitting should be _____megohm(s) or less in order for the hardware to pass the test.

    • .5

    • 1

    • 2

    • 5

    Correct Answer
    A. 1
    Explanation
    During a continuity test for fuel dispensers, the resistance reading between the nozzle spout and the dispenser fuel-outlet fitting should be 1 megohm or less in order for the hardware to pass the test.

    The area around a fuel storage dike should have a minimum slope of ________%.

    • 1 %

    • 2 %

    • 3 %

    • 4 %

    Correct Answer
    A. 1 %
    Explanation
    The area around a fuel storage dike should have a minimum slope of 1%. This slope is necessary to ensure proper drainage and prevent the accumulation of fuel or other hazardous materials. A steeper slope could lead to runoff and erosion issues, while a flatter slope may result in stagnant water or pooling of fuel. Therefore, a 1% slope strikes a balance between effective drainage and stability.

  • 8. 

    Sections of sagging line conductors should not be longer than _______.

    • 1000 feet

    • 1 mile

    • 2 miles

    • 4 1/2 miles

    Correct Answer
    A. 4 1/2 miles
    Explanation
    The correct answer is 4 1/2 miles. This is because sections of sagging line conductors should not be too long in order to prevent excessive sagging and potential damage to the conductors. If the sections are too long, the weight of the conductors can cause them to sag too much, increasing the risk of them coming into contact with objects or the ground. Therefore, it is important to limit the length of sagging line conductors to ensure safe and efficient operation.

    For a suction-pumping petroleum system, the pressure-regulating valve should be installed directly under the suction pump and the hose length should be limited to ____feet.

    • 10

    • 12

    • 14

    • 20

    Correct Answer
    A. 14
    Explanation
    In a suction-pumping petroleum system, the pressure-regulating valve should be installed directly under the suction pump to regulate the pressure effectively. Additionally, the hose length should be limited to 14 feet. This limitation ensures that the system operates efficiently and minimizes the risk of pressure loss or other issues that may arise from excessive hose length.

  • 10. 

    The minimum polyethylene tube width for a 10 inch push-on joint pipe is _____inches.

    • 12

    • 14

    • 18

    • 24

    Correct Answer
    A. 24
    Explanation
    The minimum polyethylene tube width for a 10 inch push-on joint pipe is 24 inches. This means that the polyethylene tube used for the joint pipe should have a width of at least 24 inches to ensure proper fit and functionality. A wider tube allows for easier installation and better sealing of the joint, ensuring a secure connection between the pipes.
