“…For the (methane + ethane) system, the data by Costa-Gomes and Trusler [103] reached a maximum deviation of 0.282% on the isotherm of T = 275 K at p = 12.5 MPa and methane mole fraction of 0.84902; also, the Younglove et al data [105] reached a maximum deviation of −0.246% on the 350 K isotherm at p = 9.4 MPa and methane mole fraction of 0.94985. For the (methane + nitrogen) system, the most departed results were for the Estela-Uribe et al [109] data on the 220 K isotherm at pressures between p = 12.5 and 19.5 MPa at mole fraction of methane of 0.80037. For the (methane + carbon dioxide) system the maximum deviations occurred for the Estela-Uribe et al [109] data on the 450 K isotherm at pressures up to p = 17.3 MPa.…”

Thus, the overall pattern of deviations is that those increased the lower the temperature and the higher the pressure.…”

An Apparatus Based on a Spherical Resonator for Measuring the Speed of Sound in Gases and for Determining the Boltzmann Constant

The Spanish Metrology Institute and the Research Group TERMOCAL of the University of Valladolid are involved in a European project for which the main target is the determination of the Boltzmann constant k B . We have set-up an acoustic gas thermometer, which consists of a stainless steel spherical resonator, 4 cm nominal radio, in an adiabatic enclosure. The temperature stability and uniformity obtained are about 0.1 mK. This system allows performance of measurements of acoustic and microwave resonance frequencies. Microwave measurements characterize the resonator volume. Both hemispheres, joined by a flange in the equatorial band, can be misaligned up to 50 µm, splitting degenerate microwave modes in suitable triplets. Acoustic radial resonances in helium and argon can be used to compute the zero-density limit at the speed of sound at T TPW . Kinetic theory of gases and hydrodynamics reveals k B from this speed of sound value. In this article, a description of the apparatus and the first results using argon will be presented.
