Air is compressed by a compressor from an inlet state of 100 kPa and 300 K to 1000 kPa . Find the work per unit mass for the processes. (a) Isentropic compression with
k=1.5
(b) Polytropic compression with
n=1.4
(c) Isothermal compression (d) Ideal two-stage polytropic compression with
n=1.4
(e) Ideal three-stage polytropic compression with
n=1.4
