Question

If a pump develops 10 bars of pressure and has a flow rate of 1500 l/min, what will be the pump motor power at 90 %

efficiency? kW
​

Answer 1

Answer:

For every pressure, the pump will only deliver one specific flow rate. Therefore, to control the flow of a centrifugal pump, simply set the output pressure to the point on the P-V diagram that allows the pump to deliver the desired flow rate. The output pressure of the pump is set using a back pressure regulator.
