centrifugal pump lifts water against a head of 40m with a manometric efficiency of 75%. The suction and delivery ipes both have a diameter of 125mm. The impeller external diameter is 350mm and is 20mm wide at outlet; its exit igle is 25deg. There is a friction loss of 8m in the pipeline when running at a speed of 1440rpm. Sketch the blade velocity diagram and calculate the discharge. Calculate the increase in pressure head from the inlet flange to the exit of the impeller if H loss impeller is 1,5m [15]
