Description: actual volumetric efficiency of the pump; Name: volumetricefficiency
Description: determined ratio of the actual delivered volume at maximum pressure to the geometric displacement volume; Name: Volumetric efficiency
Description: Speed that characterizes a pump in terms of its speed, flow rate per impeller eye, i.e. total flow for single-flow impeller, half flow for double-flow impeller, at the best efficiency point and head per stage at maximum impeller diameter ; Name: Specific speed
