Helium-4 actually has a lower flow velocity than the sound velocity, but this model is useful to illustrate the concept.
What sound velocity data have been used to"correct" the echo sounding data and how accurate are they?
Note that measurement of sound velocity requires that the thickness of the test piece be known.
Angular Variation in Wedges: With any high temperature wedge, sound velocity in the wedge material will decrease as it heats up,
It is possible to have a substantial difference in sound velocity between two otherwise identical castings containing the same percentage of graphite, one with the graphite in flake form(gray iron) and the other with spherical graphite nodular iron.
including sound velocity used and accuracy of location
Because the sound velocity of gray iron is lower than that of nodular iron,
which can provide a direct readout of sound velocity based on an entered part thickness.
A potential limitation is that the accuracy of measurement is only as good as the accuracy to which material and sound velocity is known, and is there for subject to inaccuracies if material sound velocity changes unpredictably.
he showed that helium-4 flowing past a wall would not spontaneously create excitations if the flow velocity was less than the sound velocity.
acoustic receivers, sound velocity sensors.
In the 1970s, under his leadership, an experimental device was created at the institute to measure sound velocities at temperatures up to 650 K
Sound velocity can be easily measured using ultrasonic pulse-echo techniques with appropriate equipment.
Large inserts that fill most of the volume of the bar can also be detected through changes in sound velocity.
If the sound velocity in a bar deviates from the expected value,
Any ultrasonic thickness measurement will be accurate only to the degree that material sound velocity is consistent with gage calibration.
Sound velocity can vary in both ferrous
Cable multiparameter stations for carrying out year-round seismoacoustic studies in the ultralow-frequency range with simultaneous measurement of hydrophysical parameters of the medium sound velocity, temperature, pressure, flow velocity. .
Note that because of the lower sound velocity in cast iron
For dedicated velocity measurement, all Olympus precision thickness gages can provides a direct readout of sound velocity in cast iron and other materials based on an entered thickness calibration.
