Correlation of Pressure Undershoot During Hot-Water Depressurization

Abstract

A method is devised for correlating the extent that the pressure of a system undershoots the saturation pressure during a rapid depressurization in water. The dependent variables in the correlation are the initial water temperature and the depressurization rate. The correlation is motivated by classical nucleation theory, and based on data from a variety of sources. The probable error of pressure undershoots predicted by the correlation is ±10.4 percent.
