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.

5: 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

You can find the answer here >

5: 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

5: 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
