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: 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
