Extracted text: 3.14 The following data refer to an axial flow blower with a single stage: Mass flow rate=0.75 kg/s Rotor tip and hub diameters=24 cm and 16 cm Rotational speed=3500 rpm As the air flows through the rotor, it turns through an angle of 22° away from the axial direction. Assuming standard atmospheric conditions and that the axial velocity is a constant, compute the degree of reaction and power input to the blower. Also, find the utilization factor. Inlet absolute velocity is purely axial. Ans: P=-252.8 kW; R=0.875
