Water is contained in a closed rigid tank at an initial pressure of 1200 kPa. Heat transfer occurs until the pressure increases to 7 MPa and the tank found to be containing 1,78 kg saturated liquid, and the mass of the saturated vapor is 0.22 kg. Determine the initial temperature, entropy and enthalpy of the water.
