A global Helmholtz function accurately representing the thermodynamic properties of isobutane-isopentane mixtures over a wide range of temperatures and pressures has been developed. The Helmholtz function has been used for the generation by computer of tables and charts of properties of interest to designers of power cycles. This Helmholtz function has also been extended to allow for additional components in the mixture, thus enabling the accurate calculation of corrections to the thermodynamic properties when impurities are present in significant amounts.
