The High Pressure Sound Velocity and Equation of State of Aqueous Solutions of Hydroxylammonium Nitrate and Triethanolammonium Nitrate

Abstract

A cell for high pressure sound velocity measurements of liquids was designed and used in a Birch-Bridgman high pressure system with a liquid propellant specimen. The dependence of the sound velocity on pressure to 4.2 kbar (4200 atmospheres) was measured at room temperature and on temperatures between 220 and 293 K at room pressure. These data, together with the temperature dependence of the specific heat which was also measured and some thermodynamic arguments, were used to obtain the full equation of state with temperature and the pressure dependence of the specific heat and of the volume expansitivity at room temperature. We compare our results with data obtained by volumetric and other ultrasonic measurements. Keywords: Equation of State, Liquid propellants, Thermodynamic properties, Ultrasonics, Liquids.
