Reconsider Prob. 4-16. Using the EES (or other) software, plot the process described in the problem on a P-V diagram, and investigate the effect of the poly-tropic exponent n on the boundary work. Let the poly-tropic exponent vary from 1.1 to 1.6. Plot the boundary work versus the poly-tropic exponent, and discuss the results.
Prob. 4-16
processes in piston-cylinder devices, the gases have been observed to satisfy the relationship PVn =C, where n and C are constants. Calculate the work done when a gas expands from 150 kPa and 0.03 m3 to a final volume of 0.2 m3 for the case of n= 1.3.
