Abstract
In one embodiment, a technique is disclosed for calculating a relative pump speed factor for attaining a prescribed hydraulic head or for pumping a prescribed amount of flow. A hydraulic model of a water distribution or collection system is defined to include link elements and node elements. At least one of the node elements represents a fixed-flow variable speed pump (VSP) that delivers a desired amount of flow, a variable speed pump battery (VSPB) that represents multiple VSPs operating in parallel with each other, a VSP with a tank located on the VSP's discharge side, or a VSP with a tank located on the VSP's suction side.
