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
Q: How do we calculate head requirement from the pump?
A: Elevation lift + static water level + drawdown in the well + pressure head of the application device + friction loss in the pipes
Q: How do we calculate head requirement from the pump?
A: Elevation lift + static water level + drawdown in the well + pressure head of the application device - friction loss in the pipes
