A system consists of 2 kg, of carbon dioxide gas initially at state 1, where p₁ = 1.5 bara, T₁ = 400K. The system undergoes a power cycle consisting of the following processes: Process 1-2: Constant volume to p2 = 2.25p1 Process 2-3: Expansion with pv = constant where n = 1.33 Process 3-1: Constant-pressure compression Assuming the ideal gas model and neglecting kinetic and potential energy effects, sketch the cycle on a p-v diagram.
