Question

5 kg steam expands in a piston-cylinder device from a pressure of 5 bar and
700°C (h=3925.97 kJ/kg s=8.5892kJ/kg-K, u=3477.52 kJ/kg) to a pressure and temperature of 3 bar and 600°C(h=3703.20 kJ/kg s=8.5892kJ/kg-K, u=3300.79 kJ/kg ).If the process is reversible and adiabatic, calculate the total work(kJ) for the process
