A centrifugal water pump is driven at a speed of 1450 rpm. The pump impeller is of radial type and has an average radius of 50 mm at the vane inlet and a radius of 150 mm at the vane exit. The vane width at inlet and exit are 25 and 10 mm respectively. The vane angles are ?1 = 500 and ?2 = 300. Assuming no prerotation at inlet and neglecting all sources of losses, determine

a. the volume flow rate

b. the output fluid power

c. the static pressure rise through the impeller.

When operated at N = 1170 rpm, a centrifugal pump, with impeller D = 8in., has a shutoff head ho = 25.0 ft of water. At the same operating speed, best efficiency occurs at Q = 300 gpm, where the head is h = 21.9 ft of water. Fit these data at 1170 rpm with a parabola. Scale the results to a new operating speed of 1750 rpm. Plot and compare the results.
