A system consists of 2 kg of carbon dioxide gas initially atstate 1, where p1 = 1 bar,T1 = 300 K. The system undergoes a power cycleconsisting of the following processes:
Process 1–2: Constant volume to p2 = 4bar.
Process 2–3: Expansion with pv1.4 =constant.
Process 3–1: Constant-pressure compression.
Assuming the ideal gas model and neglecting kinetic and potentialenergy effects, calculate thermal efficiency.
