connections similar to a dry hydrant for quick fire department hook-ups?

a. Agricultural irrigation systems
b. Large indoor or outdoor pools
c. Cisterns
d. Small private residential pools

Answer 2

Question 3

When drafting, water is forced in and continues to rise until the pump is full of water or:

a. pressure within the pump and intake hose begins to vary.
b. pressure within the pump and intake hose is less than atmospheric pressure.
c. pressure within the pump and intake hose equals atmospheric pressure.
d. pressure within the pump and intake hose is greater than atmospheric pressure.

Answer 3

c. pressure within the pump and intake hose equals atmospheric pressure

Question 4

Low-level strainers are most
commonly used to draft from:

a. portable water tanks.
b. running streams or creeks.
c. lakes.
d. small ponds.

Answer 4

a. portable water tanks

Question 5

Theoretical lift can be calculated by determining the actual atmospheric pressure of an area and:
Select one:
a. subtracting that number from the water’s pressure per square foot (kPa) while it is in the intake hose.
b. dividing that number by the water’s pressure per square foot (kPa) while it is in the intake hose.
c. multiplying that number by the water’s pressure per square foot (kPa) while it is in the intake hose.
d. adding that number to the water’s pressure per square foot (kPa) while it is in the intake hose

Answer 5

c. multiplying that number by the water’s pressure per square foot (kPa) while it is in the intake hose

Question 6

When providing flow required to reach the capacity of the pumping apparatus, floating strainers may be used for water as shallow as:
Select one:
a. 1 foot (300 mm)
b. 3 inches (75 mm)
c. 6 inches (150 mm)
d. 8 inches (200 mm)

Answer 6

a. 1 foot (300 mm)

Question 7

When at draft, the sum of the pump discharge pressure and intake pressure correction that takes into account friction loss in the intake hose and height of the lift is called:
Select one:
a. average pump discharge pressure.
b. theoretical pump discharge pressure.
c. practical pump discharge pressure.
d. net pump discharge pressure.

Answer 7

d. net pump discharge pressure.
