Need help going through the process of solving this problem to see where I'm going right, and where I'm going wrong One kg of carbon dioxide (CO2), in a piston-cylinder assembly, initially at 90°F, 30 lbf/in^2, is compressed isothermally to a final pressure of 110 lbf/in^2. During compression, the nitrogen rejects energy by heat transfer through the cylinder’s end wall, which has inner and outer temperatures of 90°F and 80°F, respectively. Let T0 = 80°F, and P0 = 15.5 lbf/in^2. Using the ideal gas model for the carbon dioxide. Consider carbon dioxide as the system: a. Determine the amount of work required for the compression, in Btu. b. Determine the exergy transfer accompanying the work, in Btu. c. Determine the exergy transfer accompanying the heat transfer, in Btu. d. Determine the exergy destroyed during the process, in Btu.
