Argon enters a compressor at steady state flow rate of 1 kg/s with pressure P_1=1 bar and temperature T_1=27C and exits at a pressure of P_2=5 bar and temperature T_2=400C. There is no significant heat transfer with the surroundings, and kinetic and potential energy effects can be ignored. Find the following:
1. State your assumptions/observations
2. Sketch the 'actual' and 'int. rev.' compression processes on T-s diagram?
3. Find actual power W_c required for compressor operation (in kW)?
4. Find minimum theoretical power W_c,min required for compressor operation (in kW)?
5. Find isentropic efficiency of compressor operation?
6. Find temperature at the compressor exit for isentropic operation T_2s (in degrees C)
