Book excerpt: Correlations based upon empirical modified equations derived from kinetic theory were developed for the thermal conductivity and viscosity of gas mixtures. The conductivity equation was compared to 226 binary mixture conductivities in temperatures from 0 to 774 deg C from the literature and this work. The average deviation is 2.1%. In correlating conductivity data of mixtures of polyatomic molecules, the energy transport is considered in two parts, i.e., one protion transferred by collision and the other by diffusion. The proposed viscosity equation reproduces 103 binary data points with an average deviation of 1.3%. These equations are more consistent with experiment than existing correlations in the literature. the relation of the conductivity or viscosity to composition and temperature are discussed in the light of the proposed equations. It has been demonstrated that, at a given composition, the ratio of the measured conductivity to that calculated on the molar average basis for mixtures of most simple molecules and the ratio of the measured viscosity to that calculated on the molar average basis for mixtures of most gases should be nearly constant over a temperature range of 200 to 300 deg C. The thermal conductivity of ten gases and selected binary and ternary mixtures of them were measured in a concentric silver cylinder cell in the temperature range of 100 to 540 deg C The gases are He, A, N/sub 2/, O/sub 2/, CO/sub 2/, CH/sub 4/, C/sub 2/ H/sub 4/, C/sub 3/H/sub 8/, methyl ether, and methyl formats.

Brokaw and published by . This book was released on 1961 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: In problems involving fluid flow, heat transfer, and mass transfer of gases, the viscosities, thermal conductivities, and diffusion coefficients are required. Direct measurements are in any event time consuming--they may be impossible. Alignment charts (nomographs) for calculating the low-pressure transport properties of nonpolar gases and gas mixtures are presented. Calculations for pure gases are based on the rigorous kinetic theory of gases as applied to a realistic intermolecular force law. Mixture viscosities and conductivities are calculated from good approximations derived from rigorous theory. Properties can be calculated quickly with a precision of 2 percent or better. Accuracy depends on how well the constants characterizing the intermolecular force law are known; if constants are derived from experimental data, results should be accurate to 5 percent or better. Force constants for 65 gases are tabulated.

This book was released on 1962 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plots of property data of 380 gases and of 84 elements and compounds considered as gases display correlations which allow convenient estimation of missing data. Constants needed for the estimation of properties of gas mixtures correlate in the same fashion. It appears to be possible to rapidly estimate specific heat, viscosity, and thermal conductivity of gases and constants needed for the prediciton of mixture properties if only the empirical chemical formulas of the gases are known. The method allows a broad survey over the entire field of available gases. (Author).

This book was released on 1994 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamic properties of gas mixtures are not always well approximated by the average properties of pure gases weighted by the fractional composition. In order to improve our calculations we have turned to the literature to find formulas said to be useful for calculating the properties of mixtures in the range of temperatures and pressures encountered in human diving. Very little has been published on experimental determinations of properties of mixtures, so we have sought principally to verify that the formulas for mixtures give a good match to data on pure gases. In order to match data on pure gases, the values for the critical temperature (TC) and the critical pressure (PC) for H2 and He were modified. In addition, ad-hoc adjustments have been made to the critical volumes (VC) to make viscosity at low pressures match tables for these two gases. Omega, the acentric factor in the formulas, is taken as zero for all gases. The properties for which we have subroutines are thermal conductivity in watts/meter x degree/ K, viscosity micropoise, density in moles/cu cm, heat capacity in Joules/mole x degree /K, and the vapor pressure of water in torr.
