Description: Absolute energy level in the inlet cross-section of the pump at the operating point above the level corresponding to the vapor pressure in relation to the NPSH reference level.; Name: nom NPSH
Description: absolute total inlet head above the head equivalent to the vapor pressure based on the NPSH at the operating point; Name: NPSH-nominal
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
