Abstract
A Helmholtz function for mixtures of isobutane and isopentane has been formed based upon a recent correlation of pure isobutane as the reference fluid and using extended corresponding states principles. This function can be used to generate other thermodynamic properties of interest by differentiations with respect to its independent variables, V, T and X. Sample table of properties generated this way and a pressure enthalpy chart of interest to the designer of geothermal power cycles are presented.
