β¦ Synopsis
A simple equation of state based on a modification to the Tait equation is described. The use of non-linear regression methods allows the equation to be fitted to data sets and the (p-v-t) surface can then be predicted. The equation yields predicted values of volume with a high level of accuracy. Its use for predicting other thermodynamic properties of liquids is explored.
INTRODUCTION.
Measurement of (p,v,t) for pure fluids provides fundamental information for calculating the pressure (p) and temperature (t) dependence of the various thermodynamic properties of the fluid. These thermodynamic data provide useful parameters for other theoretical studies.
