Bulk modulus of water at 20000 psi

[trianglytoast]

Homework Statement

For a university project I have to design a safety enclosure for hydrostatic testing at pressures up to (20000 psi) on equipment with maximum volume 8m³. I am having difficulty finding data to calculate the expansion energy of water in the event of a sudden brittle failure. I cannot find any data for pressures this high, and given that I only have a fixed volume, cannot use the formula relating volume change to bulk modulus. The water is taken from the tap, so going to use a range of 10-20°C. Any help would be greatly appreciated.

Homework Equations

u= 0.5βP²V

where:
u = liquid strain energy
β = bulk modulus of the liquid
P = pressure
V = volume

The Attempt at a Solution

I have found values for pressures up to 550 bar and was planning to linearly extrapolate, however I'm unsure if this is accurate.

I have looked at the relationship between strain energy and temperature, however I am unsure how to factor this in.
