A10 stage axial flow compressor develops an overall pressure ratio of 8.0 with and isentropic efficiency of 0.85. the absolute velocity component of air enters the rotor at an angle of 27â° to the axial direction. the axial component of velocity is constant throughout the compressor and is equal to 150 m/s. if the ambient air conditions are 15â°c and 1 bar, determine the angle which the relative component of velocity makes with the axial direction at the exit of the rotor.
