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 ...
Design and construction of apparatus for determining the velocity of sound in gases at high pressures and temperatures
The purpose of the present work ie to present results obtained from studies using a variable path type interferometer designed for generating sound waves above the audible limit in gases at high pressures and temperatures. ...
