A rotor in a compressor stage has a mean blade radius of 0.285 m and an angular rotor velocity of 8500 RPMs. The static temperature and velocity at the rotor inlet are 288 K and 160 m/s. The rotor turning angle is 10 degrees. Assume that the axial velocity is constant through the stage and that the flow enters the rotor and exits the stator in the axial direction. a. Compute the power per unit mass flow rate required by
