Super-heated steam at 4 bar and 400 °C is cooled at constant pressure to saturated vapor.
Determine the following:
1- Enthalpy change from steam tables.
2- Enthalpy change from heat capacity data.
3- Density of steam and the internal energy change.
4- Draw the PV diagram for this process.
Cp (water vapor) =33.46 +0.00688 T +0.7604 × 10-5 T?
Cp in (J/mol.K) and T in K.
