Abstract

Disclosed is a method of determining the instantaneous pressure produced by the pump (and the internal SG that goes along with that) and how that can be used in relation to the overall total pipeline resistance to control and/or adjust the pump performance to better operate the pump and/or reduce or eliminate the unsuitable unstable operation and all of the adverse cavitation, wear and other effects on the pump and pipeline that go along with unstable operations.
