A gas undergoes a cycle in a piston-cylinder assembly consisting of the following three processes: Process 1-2: Constant pressure, p = 1.4 bar, V1 = 0.028 m3, W12 = 11.5 kJ Process 2-3: Compression with pV = constant, U3 = U2 Process 3-1: Constant volume, U1 – U3 = - 24.5 kJ Kinetic and potential energy effects are negligible.
(a) Calculate the net work for the cycle, in kJ.
