Question:
Work and heat transfer calculation in a closed system
Find the pressure, temperature and volume at the end of each of the four processes. Then calculate the work done during each process and the net amount of work done. Finally calculate the net amount of heat transfer comparing the very initial and the very final states.
Nitrogen T1 (°C): 90, P1 (kPa): 530, m(kg): 9.3
process1: Isobaric expansion and the volume increased by 70%
process2: Isothermal expansion to a pressure of 10% of the initial pressure.
process3: Polytrpic comprission with n = 1.2 to the same initial process.
process4: Isochoric cooling to reach a pressure equal to 40% of the initial pressure
