Manometric head, in case of a centrifugal pump, is equal to

Work-done per kN of water Losses within the impeller

Energy per kN at outlet of impeller Energy per kN at inlet of impeller

All of these

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
