1. What is the primary purpose of a pump in a water-supply system?
a. To heat the water
b. To filter all suspended solids
c. To move water and provide the required flow and pressure
d. To disinfect the water
Answer: c. To move water and provide the required flow and pressure
Rationale: A pump converts mechanical energy into hydraulic energy,
allowing water to be moved from a source to a storage or distribution
system. Proper pump selection ensures that the system receives the
required flow rate and pressure.
2. Which measurement describes the vertical distance a pump must
raise water?
, a. Flow rate
b. Head
c. Voltage
d. Temperature
Answer: b. Head
Rationale: Head represents energy per unit weight of fluid and is
commonly expressed as feet or meters of water. Static lift, friction
losses, and pressure requirements are all considered when determining
the total head.
3. What is flow rate commonly expressed in for water pumping
applications?
a. Gallons per minute
b. Ohms per foot
c. Pounds per square inch
d. Volts per ampere
Answer: a. Gallons per minute
Rationale: Gallons per minute (GPM) is a common unit for describing
the volume of water delivered by a pump over time. Pump performance
charts frequently specify flow in GPM.
, 4. What is the purpose of a well screen?
a. To increase motor voltage
b. To prevent all water from entering the well
c. To allow groundwater into the well while retaining formation
material
d. To store electrical energy
Answer: c. To allow groundwater into the well while retaining
formation material
Rationale: A well screen permits groundwater to enter the well while
limiting the movement of sand and other formation particles. Proper
screen selection is important for maintaining well performance and
protecting pumping equipment.
5. Which component prevents water from flowing backward through
a pump system?
a. Check valve
b. Pressure gauge
c. Pressure switch
d. Flow meter
Answer: a. Check valve
, Rationale: A check valve permits flow in one direction and automatically
closes when flow reverses. This helps prevent backflow and can reduce
pressure surges and unnecessary pump cycling.
6. What is the main function of a pressure tank in a water system?
a. To eliminate the need for a pump
b. To store pressurized water and reduce pump cycling
c. To remove dissolved minerals
d. To increase motor horsepower
Answer: b. To store pressurized water and reduce pump cycling
Rationale: A pressure tank stores a volume of water under pressure so
that small demands can be supplied without immediately starting the
pump. This reduces frequent starts and stops, which can extend pump
and motor life.
7. A pressure switch is commonly used to control what?
a. Water temperature
b. Pump starting and stopping
c. Well depth
d. Pipe diameter
Answer: b. Pump starting and stopping
