The following results were obtained from a test on a small single-sided centrifugals compressor:

Determine the isentropic efficiency of the compressor. The diameter of the impeller is 0.165 m, the axial depth of the vaneless diffuser is 0.01 m and the number of impeller vanes is 17. Making use of the Stanitz equation for slip factor, calculate the stagnation pressure at the impeller tip.
