Undersaturated Water Isothermal Compressibility Coefficient (Cw,us)
The compressibility (also known as the coefficient of compressibility or isothermal compressibility is a measure of the relative volume change of a fluid or solid as a response to the application of pressure.
The compressibility of water is a function of pressure and temperature and it is a key factor in transient flows.
