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
01: Suction lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes Your answer
02: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
03: Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes
