Characteristics curve of pump
WebIn the pumping system, there are two characteristic curves that determine the operating point of the pump. One is related to the pump itself, which is called the pump … WebApr 12, 2024 · A pump curve is a graphical representation of a centrifugal pump’s performance characteristics. It shows the relationship between the flow rate (Q), head (H), and power consumption (P) of a pump at different operating points. The pump curve is generated by testing the pump in a laboratory and plotting the data on a graph.
