3: How do we calculate head requirement from the pump?
Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes

3: How do we calculate head requirement from the pump?
Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
3: How do we calculate head requirement from the pump?
Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes

4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
There is no elevation lift and the drawdown has to be added to the suction lift.

4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
There is no suction lift. Instead there is static water table and the drawdown has to be added to the elevation lift.
4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
There is no suction lift and the drawdown has to be deducted from the elevation lift.
