# Heating suprecritical water in a closed water tank

How does the pressure of water in a closed tank evolve in the following setting: - closed tank of 2 liters (filled up with water) - water initially at 25°C and pressurized to 3 bars

The water is now heated up to 130°C, thus remaining a fluid (based on water property tables). The specific volume of water increases roughly by 6% due to the temperature increase. Since the water is in a closed tank, it cannot expand, thus the pressure needs to increase.

Which equation will allow me to calculate the resulting pressure in the water tank?

Thanks in advance for any hints and help
