Subject: Corresponding States for Real Gases
Status: R


Does anyone know where I can look up a set of equations that give Z(Tr,Pr)
-- ie, the compressibility factor as a function of reduced T and P -- for
the "consensus" of real gases?  I mean the set of curves including the ones
illustrated in Fig. 1.8 in Moore's Physical Chemistry, 3rd Ed., and also
in most other p-chem texts.

I'm thinking of putting together a teaching exercise using Mathematica which
will introduce functions of several variables and partial derivatives
in the context of the PVT properties of real and ideal gases;  obviously,
it could be extended to cover fugacity as well.

I think it ought to be fun to view the Z(Tr,Pr) surfaces given by
the various common equations of state, as well, but these are easy to
generate.  I'm interested for the moment on a fit to the real-gas data.
Of course it would also be nice to be able to also superimpose data
for individual real gases.....  but for now, my original request stands.

Any pointers?
