When operated at N = 1170 rpm, a centrifugal pump, with impeller D = 8in., has a shutoff head ho = 25.0 ft of water.

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.
