WebHow to select a pump Total flow rate, Q First the flow rate, Q of the pump must be determined by adding all the flow rates at each outlet of the piping system. Quantity of fluid delivered by the pump in the unit of time, generally expressed in m 3 /h. Q = A x v A (area of the pipe): π x (d/2)2 [m 2] v: speed of liquid (water) in the pipe [m/s] Web12 apr. 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.
