Question
A vessel contains water. The conditions of the system are:
- volume of the vessel: V = 0.10 m3
- presure of water: P = 200.00 kPa
- mass of water: m = 5.00 kg
- specific volume of the saturated water at the pressure: vf = 0.001061 m3/kg
- specific volume of the saturated vapor at the pressure: vg = 0.885780 m3/kg
- enthalpy of the saturated water at the pressure: hf = 504.71 kJ/kg
- enthalpy of the saturated water at the pressure: hg = 2706.30 kJ/k
- difference of enthalpy of the saturated vapor and saturated liquid at the pressure: hfg = 2201.60 kJ/kg
Determine (5) the enthalpy per unit mass of water in the vessel, h=_____ kJ/kg

- A large tank is divided into two equal volumes. One half of the tank is filled with saturated water of unknown quality at temperature = 320 °F. The other half of the tank is evacuated (i.e there is nothing in it). When the partition separating the two halves breaks, the water will expand to fill the entire tank. The temperature is unchanged, and the final pressure is given below. Determine the quality of the water before the partition broke.
