Solve Problem 12.55 using specific heats CP = h/T, from Table A.8 at 1000 K. A mixture

Question:

Solve Problem 12.55 using specific heats CP = ∆h/∆T, from Table A.8 at 1000 K. A mixture of 50% carbon dioxide and 50% water by mass is brought from 1500 K, 1 MPa to 500 K, 200 kPa in a polytropic process through a steady state device. Find the necessary heat transfer and work involved using values from Table A.5.
