Description: Flow rate measured in the pump inlet nozzle divided by the inlet cross-section of the pump; Name: mean speed in entry
Description: Measured rate of flow at pump inlet connection divided by the inlet area of the pump; Name: Mean velocity at inlet
Description: net positive suction head (NPSH) from flow rate at best efficiency point for actual impeller (indication of the minimum inlet pressure in meters required for the pump to deliver according to the QH curve. related to the optimum duty point at the current impeller diameter); Name: net positive suction head for Q opt at actual impeller size
