A) A centrifugal compressor is running at 16000 rpm. The stagnation pressure ratio between the impeller inlet and outlet is 4.2. Air enters the compressor at stagnation temperature of 20 C and 1 bar. If the impeller has radial blades at the exit such that the radial velocity at the exit is 136 m/s and the isentropic efficiency of the compressor is 0.82 Calculate slip factor. Assume axial entrance and rotor diameter at the outlet is 58 cm. hint Cp = 1005 J/kg.k and y = 1.4
