Air is compressed steadily by a reversible compressor from an inlet state of 100kPa and 300K to an exit pressure of 900kPa. Determine the compressor work per unit mass for

a) The isentropic compression with k=1.4

b) A compressor with 85% isentropic efficiency

c) Two-stage compression (100kPa to 300kPa, and 300 kPa to 900 kPa) with intercooling with an isentropic efficiency of 85% for both compressors

Step 1

(a)First we have to find the compressor work pressure wi...
