摘要: The velocity of sound waves having a frequency of 108,600 cycles per second, has been measured in water vapor by a method similar to that used by Pierce for other gases. At a temperature of 27° C. the velocity is 432 meters per second.关键词:...
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 ...
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 elastic constants of crystals are commonly determined by measuring the velocities of propagation of acoustic waves in different principal crystal directions and applying well-known formulae 1 . For crystals of high perfection it has generally been reported that the measured velocity of sound of a...
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》 被引量: 60发表: 1954年 Compressional wave attenuation in oceanic basalts measure...
The phase velocity of ultrasound was measured in suspensions of spherical glass particles in water with particle size parameters (particle size / wavelength) ranging from ca. 0,01 to 40. Two different measurement techniques have been tested: i) A narrow-band tone-burst (tb) setup with compariso...
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 ...
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 ...
Ultrasonic Flowmeter and Velocity Meter for the Components of a Multiphase Stream A new method proposed for measuring the velocity and flow rate of the components of a multiphase stream of gas, oil, and water is based on statistical proc... VP Drobkov,VI Mel'Nikov,SA Labutin - 《Measureme...
