Q: Identify the factors that are not considered for calculating the total pump head requirements?
A: Elevation lift
01: Friction losses
03: Pump flow
Q: Identify the factors that are not considered for calculating the total pump head requirements?
A: Pump flow
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: 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.
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.
