An adiabatic compressor receives 0.5 kg/s of helium at 175 kPa and 320 K and

discharges it at 0.8 MPa. If the specific heat at constant pressure and specific heat at

constant volume of helium is 5.19 and 3.12 kJ/(kg-K) respectively, Calculate the

following.

a. The volume flow rate of helium in cfm.

b. The Work of the compressor in kW.

c. The brake power in Hp for a compressor efficiency of 78%.
