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. P8.111. It now expands in a reversible polytropic process with exponent, n = 1.5, through a volume ratio of 8:1. Show this process on P–v and T–s diagrams, and calculate the work and heat transfer for the process.
