During some actual expansion and compression

Reconsider Prob. 4–12. Using the EES (or other) software, plot the process described in the problem on a P-V diagram, and investigate the effect of the polytropic exponent n on the boundary work. Let the polytropic exponent vary from 1.1 to 1.6. Plot the boundary work versus the polytropic exponent, and discuss the results.

Prob. 4–12:

During some actual expansion and compression processes in piston–cylinder devices, the gases have been observed to satisfy the relationship PV n = C, where n and C are constants. Calculate the work done when a gas expands from 350 kPa and 0.03 m3 to a final volume of 0.2 m3 for the case of n = 1.5.
