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 elevation lift and the drawdown has to be added to the suction lift.
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.
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 and the drawdown has to be deducted from the elevation lift.
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.
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 lower head.

A: If the pump is pumping at a higher flow, it delivers a higher head.
Q: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The efficiency of the pump
Q: Which of the following parameters is determined by the amount of water to be applied during the peak period?
A: The friction loss in the irrigation system

Q: Identify which of the following sentences are true:
A: Groundwater typically requires more treatment than surface water.
Q: Identify which of the following sentences are true:
A: To improve the filtering function, the borehole diameter must be exactly the same as the casing diameter.
Q: Identify which of the following sentences are true:
A: The drawdown is the difference between the static and the dynamic water level.
