A piston-cylinder assembly contains air at a temperature of 527°C and a volume of V1 = 2 m³. The air undergoes three processes to complete a thermodynamic cycle. The following information is known about the three steps that make up the cycle: Process 1-2: Isothermal process from P = 436 kPa to P2 = 2300 kPa Process 2-3: Isobaric process until V1/V3 = 4. Process 3-1: Polytropic process to the initial state Plot the processes on the p-v diagram and Determine: (a) The polytropic exponent for process 3-1. (b) The change in the internal energy of air for each process. (c) The work done, and heat transfer for each process. (d) The net work, and net heat transferred during the cycle.

Question
A piston-cylinder assembly contains air at a temperature of 527°C and a volume of Vi = 2 m. The air undergoes
three processes to complete a thermodynamic cycle. The following information is known about the three steps
that make up the cycle:
Process 1-2: Isothermal process from P1 = 436 kPa to P2 = 2300 kPa
Process 2-3: Isobaric process until VI/V3 = 4.
Process 3-1: Polytropic process to the initial state
Plot the processes on the p-v diagram and Determine:
(a) The polytropic exponent for process 3-1.
(b) The change in the internal energy of air for each process.
(c) The work done, and heat transfer for each process.
(d) The net work, and net heat transferred during the cycle.
