Notes:
A generalized equation of state is developed by combinin a hard-sphere equation with a truncated virial equation and generalizing the reduced hard-sphere diameter as a function of reduced temperature and acentric factor. The new equation quantitatively agrees with Pitzer's table of compressibility factor over wide ranges of gas and vapor states and is always better than the truncated virial equation. Since the terms in the equation are physically meaningful it is capable of being improved systematically by including higher virial coefficients and by using hard-core equations of state for nonspherical cores. The equation is extended to mixtures with well-developed combination rules.
