Question: Air undergoes a process from state 1 at 400 K and 200 kPa to state 2 at 900 K and 12 MPa. Estimate the change

Air undergoes a process from state 1 at 400 K and 200 kPa to state 2 at 900 K and 12 MPa. Estimate the change in enthalpy and entropy:
i) Assuming the air is an ideal gas with constant specific heats from Table B-2
ii) Assuming the air is an ideal-gas with constant specific heats interpolated from Table B-6 at 650 K
iii) Using the ideal-gas tables in Appendix F-1
iv) Using the equations of Section 7.5
v) Using the IRC Calculator
