A: There is no elevation lift and the drawdown has to be added to the suction lift.
01: There is no elevation lift and the drawdown has to be added to the suction lift. Your answer
02: There is no suction lift. Instead there is static water table and the drawdown has to be added to the elevation lift.
03: There is no suction lift and the drawdown has to be deducted from 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: 8 hours
02: 12-18 hours
03: 24 hours Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 12-18 hours Q: How many hours will a correctly sized pump run a day to meet the demand?
A: 24 hours
01: 8 hours
02: 12-18 hours Q: What determines the minimum flow of a pump?
A: The amount of water that needs to be applied to the crops during peak periods. Q: What determines the minimum flow of a pump?
A: The type of soil in the field.
01: The amount of water that needs to be applied to the crops during peak periods.
03: The cost of power for the pump. Q: What determines the minimum flow of a pump?
A: The cost of power for the pump.
01: The amount of water that needs to be applied to the crops during peak periods.
02: The type of soil in the field. Q: How do we calculate head requirement from the pump?
A: Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
01: Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes Your answer
02: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
03: Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes Q: How do we calculate head requirement from the pump?

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