Question
A perfect gas has a mass 1.2 kg and pressure 0.8 bar and volume 0.5 m3 This gas is compressed and undergoes to polytropic process according a law (PV1.3=C) until pressure become (57 (bar. And then, the gas is expanded at iso-thermal process until final volume returns to initial volume. Calculate work done in polytroic process and the change entropy in each process. Take y = 1.4 and R = 0. 288 kJ/kg.K %3D e 3:52
