Description: Measured residual force acting perpendicular to the shaft line and derived from hydraulic forces; Name: radial force on pump shaft
Description: measured residual force acting at right angles to the line of the shaft and derived from hydraulic forces; Name: radial load of pump rotor
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
