Implementation of Scaling and Extended Scaling Equations of State for the Critical Point of Fluids
1National Measurement Laboratory, National Bureau of Standards, Washington, D. C. 20234.
Abstract:
An explicit, practical procedure is suggested for transforming from the laboratory variables density (ρ) and temperature (T) into the parametric variables r and θ, which occur in various scaled representations of equations of state and of transport properties of fluids near critical points. A reasonably efficient and versatile computer program illustrating this procedure is provided. With this program, the parametric equations of state which occur in several formulations of simple, extended, and/or revised scaling are as easy to use as any other equation of state for which T and ρ are the independent variables.
