Question

Air undergoes a power cycle composed of the following processes:

• Process 1-2: Constant volume from p1 = 138 kPa, T1 = 280 K to T2 = 455 K • Process 2-3: Adiabatic expansion to v3 = 1.4v2
• Process 3-1: Constant-pressure compression with a heat loss of 56.8 kJ

Sketch the cycle on a p − v diagram. Considering a mass of air of m = 0.5 kg, and assuming air as ideal gas, determine:

a) the pressure at state 2, in kPa
b) the temperature at state 3, in K c) the thermal efficiency of the cycle
