Question details

Problem 2.4 A gas within a piston-cylinder assembly undergoes a thermodynamic cycle consisting of three processes: Process 1-2: Constant volume, V-0.028 m2, U2-U-26.4 kJ Process 2-3: Expansion with pV constant, Us U2 Process 3-1 : Constant pressure, p 1.4 bar, W3,--10.5 kJ There are no significant changes in kinetic or potential energy (a) Sketch the cycle on a p-V diagram. (b) Calculate the net work for the cycle, in kJ (c) Calculate the heat transfer for process 2-3, I kJ (d) Calculate the heat transfer for process 3-1, in kJ.
