Problem 3: A centrifugal compressor compresses air at ambient temperature and pressure of 288K and 1 bar respectively (stagnation values). The impeller tip speed is 364 m/s, the radial velocity at the exit from the impeller is 28 m/s, and the slip factor is 0.89. (flow area at the exit: 0.085 m2, compressor efficiency: 0.88) Calculate (a) the absolute air velocity at the impeller outlet, (b) stagnation temperature at the impeller outlet, (c) The Mach number of the absolute flow at the impeller tip. (d) mass flow (e) work done Assume an axial entrance at the impeller eye and radial blades.
