Description: ratio of the actual delivered volume at max. pressure to the geometric displacement volume; Name: vol. efficency
Description: ratio of the actual delivered volume at maximum pressure to the geometric displacement volume; Name: volumetric efficiency
Description: pump h(q) curve where the maximum head (peak point) and shut-off head are not coincidental, or the total head does not decline continuously as the rate of flow increases; Name: stable pump H(Q) curve
