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.
