The meaning of SUPERSONIC VELOCITY is a fluid velocity relative to a body in the fluid that is greater than the local velocity of sound in the fluid.
7.3.3.1 Description of disturbances The flow parameters are given as axial velocity u, pressure p, density ρ, speed of sound c, and Mach number M. The acoustic disturbances can be written in the following forms using standard techniques: (7.174)p′=Pm+eiαm+x+Pm−eiαm−xeiωt+m...
We establish that the dispersion curves, 蠅(k), used in analytical theories, in the case of liquid metal has the meaning of a average frequency of a spectrum of collective excitations at the given k value. The application of this method to liquid cesium at various temperatures has shown ...

In Equation 1, c is the velocity of sound in water, about 1500 meters/second. Thus, by knowing the transmitted sound frequency, fT, and declination angle of the transmitter transducer, .theta., and measuring the received frequency from a single, narrowband pulse, the Doppler frequency shift,...
Bone speed of soundBone strengthImmobilizationCatabolic stateParalysisBackgroundBone loss has been documented in adults in intensive care wards. Children admitted to pediatric intensive care units (PICU) are also exposed to many potential risk factors for bone loss such as immobilization, catabolic state...
This Letter presents the results of investigations of crack velocities within nanosecond pulses of loading in specimens of aluminum foil. It has been established that the crack velocities are close to, and even exceed, the values of the longitudinal speed of sound in aluminum. It is assumed that...
7.The method of claim 1, wherein the removing further comprises:determining one or more correction factors based at least in part on sound speed and/or a centroid frequency shift of one or more of the echoes; andcorrecting the raw velocity estimates based on the one or more correction facto...
Moreover, quantitative validation of SF is lacking; specifically, the practical meaning of particular SF values is unclear, aside from the fact that propagation failure (i.e., conduction block) is characterized by SF < 1. This study aims to resolve these limitations for our previously published...
