01: If the pump is pumping at a lower flow, it delivers a higher head.
02: If the pump is pumping at a lower flow, it delivers a lower head.
03: If the pump is pumping at a higher flow, it delivers a higher head. Your answer
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
