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: average speed given by the stroke length multiplied with the number of complete pumping cycles of the piston, plunger or piston attached to the diaphragm per minute (stroke per minute or pump crank speed); Name: piston velocity
