A centrifugal compressor has a pressure ratio of 4:1 with an isentropic efficiency of 80% when running at 15000 rpm and inducing air at 293 K. Curved vanes at inlet give the air a prewhirl of 25- to the axial direction at all radii and the mean dia of eye is 250 mm. The absolute air velocity atinletis 150 m/s. Impeller tip dia is 600 mm. Calculate the slip factor.
