COMPUTATION OF THE VELOCITY OF SOUND IN GASES

Abstract

A method is summarized for the precise computation of the velocity of sound in a real gas and of its variations with experimental conditions. Two problems are discussed: (1) the inclusion of the effects of departures of the equation of state from the perfect gas law, and (2) the computation of specific heats from spectroscopic data. The method is applied to air, and data are presented for the computation of the of the velocity in air under pressures between 720 and 820 mm Hg and temperatures between 0 deg and 30 deg C. These results are summarized in the form of correction of velocities measured at various frequencies and in this range of pressure and temperature.
