In order that flow takes place between two points in a pipeline, the differential pressure between these points must be more than
Suction lift + Loss of head in suction pipe due to friction + Delivery lift + Loss of head in delivery pipe due to friction + Velocity head in the delivery pipe
Energy per kN at outlet of impeller Energy per kN at inlet of impeller
Work-done per kN of water Losses within the impeller
