1. Hydrostatics is the study of fluid:

   1.   ?    In motion
   2.   ?    At rest
   3.   ?    Flowing through a pipe
   4.   ?    None of the above

2. Hydrodynamics is the study of fluid:

   1.   ?    Stationary in tank
   2.   ?    At rest
   3.   ?    In motion
   4.   ?    None of the above

3. Typical units of flow rate are:

   1.   ?    Square feet
   2.   ?    Cubic feet
   3.   ?    π r²
   4.   ?    Cubic feet per second (cfs)

4. One gallon of water weighs 8.34 pounds and one cubic foot of water holds 7.48 gallons. How many pounds does one cubic foot of water weigh?

   1.   ?    62.4
   2.   ?    0.89
   3.   ?    1.1
   4.   ?    92.84

5. The amount of energy possessed by a quantity of water is called:

   1.   ?    Horsepower
   2.   ?    Net positive suction
   3.   ?    Negative pressure
   4.   ?    Head

6. How do you throttle the delivery capacity of a centrifugal pump?

   1.   ?    Suction valve
   2.   ?    Discharge valve
   3.   ?    It can not be throttled
   4.   ?    Install a blind flange on the discharge

7. Water in motion that is suddenly stopped is called:

   1.   ?    Head pressure
   2.   ?    Net positive suction head
   3.   ?    Cavitation
   4.   ?    Hammer

8. The primary cause of cavitation in a centrifugal pump is from the:

   1.   ?    Suction head being too low
   2.   ?    Discharge head being too high
   3.   ?    Suction head being too high
   4.   ?    The discharge valve closed

9. What position should the suction valve of a centrifugal pump be in during start-up?

   1.   ?    Open
   2.   ?    Closed
   3.   ?    Partially opened
   4.   ?    Does not matter

10. What type of valve has a sleeve that slides up and down inside of a tube?

    1.   ?    Gate
    2.   ?    Check
    3.   ?    Butterfly
    4.   ?    Telescoping
