Q: Identify which of the following sentences are true:
A: The drawdown is the difference between the static and the dynamic water level.
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
