High head low flow
WebLow head refers to a change in elevation of less than 66 feet (20 meters), and ultralow head refers to a change in elevation of less than 10 feet (3 meters). A vertical drop of less than 2 feet (0.6 meters) will probably make a small-scale hydroelectric system unfeasible. WebIt dictates the shape of the head-capacity curve, with low Specific Speed pumps having flat or drooping H-Q curves, and high Specific Speed pumps having very steep curves. The pump shut-off flow brake horse power also increases with increasing Specific Speed values, exceeding the best efficiency flow input power requirements at “N S ” values above …
