12.13 A centrifugal water pump having an impeller diameter of 0.5 m operates at 900 rpm. The water enters the pump parallel to the pump shaft. If the exit blade angle, 2 is 25, determine the shaft power required to turn the impeller when the flow through the pump is 0.16 m/s. The uniform blade height is 50 mm. Water density is 999 kg/m.
