Notes:
Using PVT measurements available in the literature for argon, the following equation of state involving the excess properties π and τ was developed: \documentclass{article}\pagestyle{empty}\begin{document}$$ \pi = \alpha \tau + \beta \left[ {\psi + \frac{\tau }{{\tau + 1}}} \right]\frac{\tau }{{\tau + 1}} $$\end{document} where α, β, and ψ are density-dependent functions. The results of this relationship for argon have been compared with those obtained using the BWR and the Stewart et al. (1981) equations of state. The present expression was applied in a generalized manner to nitrogen, methane, carbon dioxide, and ammonia. In addition, comparisons have been made using these four substances with three generalized relationships: a truncated virial, a modified Redlich-Kwong, and the Hirschfelder-Buehler-McGee-Sutton equations of state.
