Condensation of a vapor in the presence of a non-condensing gas
Experimental measurements of the rate of condensation of ethanol in the presence of nitrogen, helium, and carbon dioxide, and of carbon tetrachloride in the presence of nitrogen and carbon dioxide were made on a vertical ...
The effect of vibrations on ordering in a copper-gold alloy
Experiments were performed to determine the effects of mechanical vibrations on ordering in CuAu. The effects of 5, 10 and 15 kc vibrations were investigated over a range of ordering temperatures of 280 to 360°C. A retarding ...
Effect of vibrations on the yield strength of a low carbon steel
Experimental results show that, when a specimen is subjected to vibration in the frequency range from 15 kc to 80 kc, the steady stress necessary to cause plastic deformation is appreciably reduced. This reduction is ...
The ultrasonic measurement in nitrogen, carbon dioxide and nitrogen-carbon dioxide mixtures at medium pressure and temperature
Velocity of sound measurements have been made in pure nitrogen, pure carbon-dioxide and mixtures of these two gases at a constant pressure of 50 psi over a temperature range from 75°F to 530°F. From the experimental data ...
An evaluation of the direct shear method for determining shearing resistance of soils
The shearing strength of the soil not only controls the resistance to failure by sliding, but also influences the ultimate compressive loads which may be applied. The shearing resistance depends on the nature of the material ...
