2: 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.
2: 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.
