Abstract : Specific heat and speed of sound data were computed for imperfect air. The thermodynamic data included the effects of two-body intermolecular forces, and the results were obtained by numerical interpolation and differentiation of the recent data of Hilsenrath and Klein (AD416040). Comparisons with previous perfect gas calculations showed small effects in the isentropic exponent gamma sub E and dimensionless speed of sound a/a sub a below one amagat and negligible effects on the specific heat data for all densities up to log rho = 2.2.
