ABSTRACT:
Wire-to-water efficiency (W) of a multi-pump system is monitored and accurately determined according to the formula: ##EQU1## wherein Q is flow through the system, HS is total dynamic head across the inlet and outlet headers of the system, E is energy input to the system to drive the pump, and K is a predetermined conversion factor. The resulting efficiency determination is provided to an operator so that the pump system may be monitored.
