3.1.1 General

This study is applicable to an ordinary pump, used at its normal operating point.

Axial thrust is the resulting axial force borne by the rotor. To calculate it, we need to know the local static pressures at all points on the machine.

By simplified theory, we mean a method of calculation in which the pressures at the rotor-stator interfaces are evaluated on the assumption that the fluid is rotating at half the local rotor speed. This...
