Transcribed Image Text:
In an axial flow air compressor producing a pressure ratio of 6/1 with air entering at 20°C the mean velocity of rotor blades is 200 m/s and the inlet and exit angles of both the moving and the fixed blades at the mean radius are 45⁰ and 15° respectively. The degree of reaction at the mean radius is 50 per cent, the work done factor is 0.86 throughout, there are 12 stages and the axial velocity may be taken as constant through the compressor. Calculate (1) the specific power input per stage and (ii) the isentropic efficiency of the compressed.
