Correct
Q: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
A: There is no suction lift. Instead there is static water table and the drawdown has to be added to the elevation lift.
Correct
Q: Which of the following options is true about a centrifugal pump?
A: If the pump is pumping at a lower flow, it delivers a higher head.
Correct
Q: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The minimum size of the pump
Correct
Q: Identify which of the following sentences are true:
A: The drawdown is the difference between the static and the dynamic water level.
Correct
Q: How do we calculate head requirement from the pump?
A: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
Correct
Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 12-18 hours
