Reconsider Prob. 9–58. Using appropriate software, study the effect of varying the compression ratio from 14 to 24. Plot the net work output, mean effective pressure, and thermal efficiency as a function of the compression atio. Plot the T-s and P-v diagrams for the cycle when the compression ratio is 20.

Data From Q#58:

Repeat Prob. 9–57, but replace the isentropic expansion  process with a polytropic expansion process with the  polytropic exponent n = 1.35. Use variable specific heats.
