Question

A system contains 0.15 𝑚3 of a gas at a pressure of 3.8 bar and 150℃ . It is expanded adiabatically till the pressure falls to 1bar. The gas is then heated at a constant pressure till its enthalpy increases by 70 kJ. Determine the total work done. Take Cp = 1 kJ/kg. K and Cv= 0.714 kJ/ kg K.
