Deviations from the normal thermodynamic behaviour have been reported in the case of halides of these metals 1 . Investigation by ultrasonic radiation 2,3 of aqueous solutions of cadmium halides showed interesting deviations from the normal behaviour of electrolytic solutions. Hence, it is expected ...
A study is made of the ultrasonicabsorption and velocity of longitudinal waves in water containing suspended algae in order to determine the effect of biological suspensions on sound propagation. The ratio α/f 2 is found to be independent of frequency and is linearly dependent on algae concentrati...
Velocity of ultrasonic waves in liquid normal and para hydrogenThe velocity of ultrasonic waves in liquid hydrogen depends upon the ortho-para concentration in the liquid. Between 14 and 20掳K the velocity in a 99.8% para mixture is about 8 m/sec or about 0.6% smaller than in the 25% ...
The Velocity of Sound in Water as a Function of Temperature and Pressure The velocity of sound in water has been measured by an ultrasonic echo technique in the temperature range from — 12°C to 129°C under hydrostatic pressur... AH Smith,AW Lawson - 《Journal of Chemical Physics》 被引...
aUltrasonic waves have a wide variety of applications over an extended range of intensity, includingcutting, cleaninganddestructionof tissue at the upper extremity, and non-destructive testing (NDT) of structures at the lower end. 超声波有各种各样的应用在扩充强度, includingcutting, cleaningand...
How is the velocity of longitudinal waves in a solid measured? The velocity of longitudinal waves in a solid can be measured using various techniques, such as ultrasonic testing, laser interferometry, or acoustic microscopy. Does the velocity of longitudinal waves in a solid vary with the type ...
accuracy by setting an ultrasonic vibrator to a conduit of a nearly rectangular section having a pair of opposite sides of a breadth similar to or not larger than a size of the ultrasonic vibrator, and propagating ultrasonic waves uniformly at each area of different flow velocities in a fluid....
Sound propagation (vector and intensity) in water is a function of its velocity. And velocity is a function of water density and compressibility. As such, sound velocity is dependent upon temperature, salinity, and pressure and is normally derived expressing these three variables (Figure 2.8). Th...
Ultrasonic radiationOptical instrumentsMeasurementAcoustic propertiesSeveral new optical methods have been developed for the measurement of sound velocities in transparent fluids. The visibility pattern from stationary, progressive and pulsed progressive waves are detected by a fast response photomultiplier tube ...
3.2.5 Ultrasonic pulse velocity It is a test method and its purpose is to measure the velocity of longitudinal waves in the concrete specimens, and this velocity is a function of the square root of the ratio of its modulus of elasticity to its density [183]. It could be able to find ...
