Unformatted text preview: rearrange Change measure Z Linear Intercept = Slope = 5 The virial expansion can be done in pressure instead of density. Along isotherm, expand Z in P about ideal gas value The pressure and density virial coefficients are related 6 Using the virial expansions for PvT properties requires the definition of the compressibility factor . Choose virial expansion 1 term virials 2 term virials Z = Pv/RT 7 Example: find v for methyl chloride at 75 bar, 600K. Critical constants: Table B.2 Tc = 416.3 Tr = 1.44 Pc = 66.8 Pr = 1.12 What phase is this? Is the virial EOS appropriate? There is an easy way and a hard way...
