    1. Air-cooled heat exchangers:

    1. are less expensive than water-cooled heat exchangers.
    2. are not as efficient as water-cooled heat exchangers.
    3. require a water hookup.
    2. The watt density of immersion-type tank heaters should never exceed:
    1. 2 to 4 watts per square inch.
    2. 4 to 6 watts per square inch.
    3. 8 to 10 watts per square inch.
    3. A hydraulic reservoir is normally sized at:
    1. 1 to 2 times pump flow in gpm.
    2. 2 to 3 times pump flow in gpm.
    3. 4 to 6 times pump flow in gpm.
    4. The main purpose of the hydraulic tank is to:
    1. hold enough fluid for the circuit.
    2. deaerate the returned fluid.
    3. cool the fluid.
    5. The symbol at right shows a line that:
    1. returns below fluid level.
    2. returns above fluid level.
    3. is on the same side as the suction line.

    6. Inlet and return lines should:
    1. terminate below fluid level.
    2. terminate above fluid level.
    3. terminate anywhere that is convenient.
    7. One can always trust the sight glass for accurate fluid volume.
    1. True
    2. False
    8. The best configuration for pump and reservoir is:
    1. pump on top.
    2. pump alongside.
    3. pump underneath.
    9. All heat in a hydraulic system comes from:
    1. wasted energy.
    2. too large electric motor.
    3. oversize piping and valves.
    10. A pneumatic system's reservoir is:
    1. sized 3 to 4 times compressor flow in cfm.
    2. sized 6 to 8 times compressor flow in cfm.
    3. the earth's atmosphere.
