Agas 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 = 5 kj process 2–3: compression with pv = constant, u3 = u2 process 3–1: constant volume, u1 - u3 = -30 kj there are no significant changes in kinetic or potential energy. (a) calculate the net work for the cycle, in kj. (b) calculate the heat transfer for process 1–2, in kj.
