A centrifugal pump is required to lift 9100 lit/s of water against a head of 6 m while running at 500 r.p.m. The velocity of flow through the wheel is 2 m/s and the manometric efficiency is 60%. The angle of vane tip with the direction of motion is 150°. Work out the following:
(i) Sketch an impeller of centrifugal pump and draw the velocity triangle.
(ii) The diameter of impeller
(iii) The width of impeller
