Question 4 20 pts Carbon Dioxide (CO2) at 1 bar, 300 K enters a compressor operating at steady state and is compressed adiabatically to an exit state of 7.94 bar, 550 K. The CO2 is modeled as an ideal gas, and kinetic and potential energy effects are negligible. Molecular weight of CO2 is 44.01. Draw a T-s diagram for the process (4 points). Determine (a) the work input, in kJ per kg of CO2 flowing. (7 points) and (b) the isentropic compressor efficiency (9 points). No need for interpolation if the entropy value is close to a temperature listed in Table A-23. (Hint: Similar to "Compressor entropy-example")
