Write a program to solve the general case of Problem 6.111, in which the initial state and the expansion ratio are input variables.
Problem 6.111
The power stroke in an internal combustion engine can be approximated with a polytropic expansion. Consider air in a cylinder volume of 0.2 L at 7 MPa, 1800 K, shown in Fig. P6.111. It now expands in a reversible polytropic process with exponent n = 1.5 through a volume ratio of 10:1. Show this process on P-v and T-s diagrams, and calculate the work and heat transfer for the process.
