Description: relationship between the pump power input and the rate of flow at given operating/rated conditions of speed and liquid; Name: pump power input curve
Description: relationship between the net positive suction head required and the rate of flow at given operating conditions of speed and liquid; Name: Pump power input curve
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
