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 (AD-416 040). 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.
