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.
1. If a certain amount of steam is produced at a pressure of 8 bar and dryness fraction 0.8. Calculate :
(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.
3. Find the specific volume, enthalpy and internal energy of wet steam at 18 bar, dryness fraction 0.85.
4. Find the dryness fraction, specific volume and internal energy of steam at 7 bar and enthalpy 2550 kJ/kg.
3. Steam at 140 bar has an enthalpy of 3001.9 kJ/kg, find the temperature, the specific volume and the internal energy.
