Question:

A cylinder/piston contains air at ambient conditions, 100 kPa and 20°C with a volume of 0.3 m3. The air is compressed to 800 kPa in a reversible polytropic process with exponent, n = 1.2, after which it is expanded back to 100 kPa in a reversible adiabatic process.
a. Show the two processes in P–v and T–s diagrams.
b. Determine the final temperature and the net work.
