Speed of Sound as a Thermodynamic Property of Fluids

Abstract
In this chapter, we review the principles of sound propagation in fluid systems. From a study of the hydrodynamic equations, sound propagation is shown to be a wave phenomenon. The speed of sound then can be derieved at any state point from a knowledge of the thermodynamic surface of the fluid of interest. Several model equations of state are reviewed, and it is shown how the speed of sound can be obtained for a variety of systems. We then focus on several fluids of particular interest, and show the behavior of the sound speed over a wide range of the temperature and pressure variables. Tabulated values of the speed of sound are given for argon, nitrogen, water, and air based on the current standard reference thermodynamic surfaces.Citation
