A system consists of 2 kg of carbon dioxide gas initially at state 1, where p1 = 1 bar, T1 = 300 K. The system undergoes a power cycle consisting of the following processes:

Process 1–2: Constant volume to p2 = 4 bar.
Process 2–3: Expansion with pv1.4 = constant.
Process 3–1: Constant-pressure compression.

Assuming the ideal gas model and neglecting kinetic and potential energy effects, calculate thermal efficiency.

A gas undergoes a process from state 1, where p1 = 60 lbf/in.2, v1 = 6.0 ft3/lb, to state 2 where p2 = 99.6 lbf/in.2, according to pv1.3 = constant. The relationship between pressure, specific volume, and internal energy is u = (0.2651)pv - 95.436 where p is in lbf/in.2, v is in ft3/lb, and u is in Btu/lb. The mass of gas is 10 lb. Neglecting kinetic and potential energy effects, determine the heat transfer, in Btu.
