The fundamental principles of the interferometer, particularly the liquid supersonic interferometer of Hubbard and Loomis, are incorporated in an instrument in which the liquid under examination may be put under pressures up to about 10,000 lb./sq. in. The instrument and the pressure device are built into a block of special cast steel 8×5×4½ inches. The results given are preliminary and merely show the performance and precision of the instrument. A curve is given showing the change of velocity of a high frequency acoustic wave of 195 kc from 1143 meters per second at atmospheric pressure to 1233 meters per second at a pressure of 3105 lb./sq. in. in carbon disulphide at room temperature. (The room temperature varied at different readings from 22.25°C to 25.41°C.)read more

Ratios of specific heat and high-frequency viscosities in organic liquids under pressure, derived from ultrasonic propagation
E. G. Richardson,R. I. Tait +1 more
TL;DR: In this article, the velocity and attenuation of plane sound waves in a number of organic liquids at pressures up to 10, 000 lb/in.2 have been made and from the velocity, the adiabatic compressibility is derived and from this, by comparison with the measured isothermal compressibility, the ratio of specific heats as a function of pressure is calculated.

Ultrasonic Speeds in Liquids at High Pressures and Equation of State
TL;DR: In this paper, the experimental technique for measuring the ultrasonic speed μ, its behavior in liquids at high pressures, and the estimation of the liquid density from the μ data are discussed, and a new attempt of the density estimation from the µ data, the liquid molar volume for these substances has been derived by means of the Peng-Robinson equation of state with reasonable accuracy.
