Water is at 9000 kPa and 300 degrees celcius and flows through a partially open valve. Pressure immediately after the valve is measured to be 600 kPa. Calculate the specific internal energy of the water leaving the valve. Neglect kinetic energy changes. (note: The enthalpy of slightly compressed liquid is essentially equal to the enthalpy of saturated liquid at the same temperature)
