# Centrifugal Pump Head Calculation Formula In Mm

In table 4, the head loss drops rapidly as the id increases.For example, transporting water through a 3.5-inch pipe results in 16.2 feet of head loss, while a 6-inch pipe has a head loss of only 1.1 feet.This reduction in pipeline head loss allows for the selection of a smaller pump.

• ## Axial Thrust Ksb

The axial thrust is the resultant force of all the axial forces f acting on the pump rotor.See fig.1 axial thrust axial forces acting on the rotor in the case of a single-stage centrifugal pumpthe axial impeller force f1 is the difference between the axial forces on the discharge-side fd and suction-side fs impeller shroud f1 fd fsmomentum fj is a force which constantly acts.
