h.w 1- Calculate the dryness fraction (quality) of steam which has 1.5 kg of water in suspension with 50 kg of steam. 2- A vessel having a volume of 0.6 m3 contains 3.0 kg of liquid water and water vapour mixture in equilibrium at a pressure of 0.5 MPa. Calculate (1) Mass and volume of liquid; (2) Mass and volume of vapour 3-Determine the missing properties and the phase descriptions in the following table for water: T, °C (a) (b) (c) (d) (e) 125 75 P, kPa 200 1000 500 850 u, kJ/kg 1600 2950 X 0.6 0.0 Phase description 4-Determine the specific volume of superheated water vapor at 10 MPa and 400°C. 5-A 1.8-m3 rigid tank contains steam at 220°C. Onethird of the volume is in the liquid phase and the rest is in the vapor form. Determine (a) the pressure of the steam, (b) the quality of the saturated mixture. 6- Find the specific volume, enthalpy and internal energy of wet steam at 18 bar, dryness fraction 0.85. 7- Find the dryness fraction, specific volume and internal energy of steam at 7 bar and enthalpy 2550 kJ/kg.
