MEASURING 14 PROPERTIES WITH THE MULTI-PURPOSE INSTRUMENT AND A TEMPERATURE FREE METHOD OF MEASURING THERMAL TRANSPORT PROPERTIES
Abstract
A multi-purpose instrument originally designed to determine seven properties was extended in its capabilities to measure additional properties. The paper describes briefly the instrument and the operational procedures and brings the results of measurements of some of the properties, namely: four properties of the instrument or its wall material, thermal conductivity of He, N2 and C4F8 (in vapor and liquid state), p-v-T data of N2, dielectric constant of N2, He, A, and C4F8- vapor and liquid, vapor pressure of methanol, thermal expansion coefficient of Benzene, index of refraction and polariability of N2. A new unsteady method was introduced for the determination of heat transfer and thermal transport properties without measuring temperature and its technique was demonstrated by heat transport observations in He, A, N2 and vacuum. Whenever possible comparison with reference data were made. The agreement was in practically all cases excellent.
