Abstract

Velocity of sound is computed for water, ammonia, Freon-12 and isobutane in two-phase mixtures in thermodynamic equilibrium. A computational method is developed which yields the sound velocity in terms of the thermodynamic coordinates of the substance (T, x) without the use of diagrams. Corresponding velocities of sound for the four substances considered exhibit a certain similarity which is examined statistically. The relationship between the sound velocity and the critical mass flux is also investigated.
