Description: mean velocity, which is the stroke length multiplied by the number of complete pumping cycles of the piston, plunger or lifting rod connected to the diaphragm per minute (strokes per minute or pump crankshaft speed); Name: piston speed
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
Description: PN (nominal pressure) is an alphanumeric variable for reference purposes, relating to a combination of mechanical and measurement properties of a pipe component. It comprises the letters PN followed by a dimensionless number (according to EN 1333/96.08); Name: Nominal pressure of the muffs, A1
