The distance travelled per unit time by a sound wave travelling in an elastic medium is known as the speed of sound. The speed of sound in a given medium depends on the elasticity and density of that medium. The higher the sound speed, the greater is the elasticity and the lower is the...
6.6 Speed of sound in a fluid The speed uw with which a small pressure wave propagates through a fluid can be shown [Shapiro (1953)] to be related to the compressibility of the fluid ∂P/∂P by equation 6.65: (6.65)uω=∂P∂ρ Assuming that the pressure wave propagates through...
Ionic Liquids (ILs) are designer solvents with very unique properties, resulting in the exponential growth of publications in the field. Speed of sound can be considered as one of the important thermodynamic properties of compounds, since many other thermophysical properties can be determined using ...

Speed of Sound in Water Because water is a much less elastic fluid than air, it transmits sound about four times faster or 1400 meters per second. It is interesting to note that sound travels at different speeds at different depths, the slowest being at about 3,000 feet below sea level....

Some experimental results on high-speed motion of models in water are presented. An empirical formula for calculating the shape of axisymmetric supercavities is derived. Qualitative features of supercavities at velocities commensurable with the speed of sound in water are described. A new method of...
In this limit, sound waves propagate with frequency ω=±csk, where cs=dP/dϵ denotes the isentropic speed of sound in the fluid, and k=|k| is the wavenumber. Small dissipative corrections can be taken into account by expressing the dissipative fluxes in a systematic derivative expansion ...
The noise level of a high-speed train is a crucial indicator of its operational quality. A significant low-frequency interior noise, referred to as ‘38 Hz’ in this context, has been detected during the operation of high-speed trains. This notable noise
