A centrifugal radial water pump has the dimensions shownin Fig. P12.10. The volume rate of flow is 0.25 ft3/s, and theabsolute inlet velocity is directed radially outward. The angularvelocity of the impeller is 960 rpm. The exit velocity as seen froma coordinate system attached to the impeller can be assumed to betangent to the vane at its trailing edge. The hydraulic efficiency is82% and the mechanical efficiency is 96%. Calculate the powerrequired to drive the pump.
