Redlich-Kwong EoS

The data I have on the Redlich-Kwong Equation of State (EoS) comes from Perry’s Chemical Engineer’s Handbook (1999).

The starting equations are:

Perry’s Eq. 4-220

With for a single component gas:

Perry’s Eq. 4-223

and:

Perry’s Eq. 4-224

Expressing it for Z, Perry’s give:

Perry’s Eq. 4-225

with:

Perry’s Eq. 4-227

In those equations, PC is the critical pressure and TC is the critical temperature.
