Description: Ratio of available pump input power and the pump delivery power that comes to light after covering the mechanical power losses, losses due to friction caused by relative motion of internal surfaces and internal leakage losses.; Name: hyd eff
Description: proportion of pump available power input, pa, which is delivered as pump power output, pu, after satisfying the losses resulting from friction due to the relative motion of internal surfaces and internal leakage; Name: hydraulic efficiency
Description: Speed that characterizes a pumps cavitation performance in terms of its speed, optimum rate of flow per impeller eye at best efficiency point and NPSH3 at best efficiency point for the first stage at maximum impeller diameter ; Name: Suction-specific speed
