5.80 Shown in Fig. P5.80 are front and side views of a centrifugal pump rotor or impeller. If the pump delivers 200 liters/s of water and the blade exit angle is 35° from the tangential direction, deter- mine the power requirement associated with flow leaving at the blade angle. The flow entering the rotor blade row is essentially ra- dial as viewed from a stationary frame. 35° 15 cm 9 cm + 3000 rpm FIGURE P5.80 3 cm
