The economiser of a steam boiler receives its feed water at 34.6°C and supplies the evaporator at a temperature of 60.1°C. The water is then heated at a constant pressure of 600kPa and delivered with a dryness fraction of 0.73. The super-heater dries and superheats the steam to a specific volume of 0.394m³/kg. Determine the: specific volume of the wet steam; 1.1 1.2 degree of superheating; (
