# Find the specific volume… steam at 18 bar. solved problem

#### Find the specific volume, enthalpy and internal energy of wet steam at 18 bar, dryness fraction 0.85.

Find the specific volume, enthalpy and internal energy of wet steam at 18 bar, dryness fraction 0.85.

(i) External work done during evaporation.

(ii) Internal latent heat of steam.

2. A quantity of steam at 10 bar and 0.85 dryness occupies 0.15 m3. Determine the heat supplied to raise the temperature of the steam to 300°C at constant pressure and percentage of this heat which appears as external work. Take specific heat of superheated steam as 2.2 kJ/kg K.
