Corresponding States for Real Gases

[shenkin ^at^ avogadro.barnard.columbia.edu (Peter S. Shenkin)]

 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?
