and gas mixtures. of gas mixtures at moderate pressures, the theoretical tools are already at hand. However, the rigorous expression for mixture viscosity is algebraically complex - it requires, first of all, the reduction of a ratio of determinants of order (v + l)/v, where v is the number of components in the gas mixture. And the elements of ...

Chat Online### A Method for Calculating Viscosity and Thermal ...

A method for calculating viscosity and thermal conductivity of a helium-xenon (He-Xe) gas mixture was employed, and results were compared to AiResearch analytical data. The method of choice was that presented by Hirschfelder with Singh’s third-order correction factor applied to thermal conductivity. Values for viscosity and thermal conductivity were calculated over a temperature range of 400 ...

A method has been developed for the calculation of the viscosity of nonpolar gas mixtures at moderate and elevated pressures from the molecular weights and critical constants of the components. By the use of available experimental data and appropriate pseudocritical constant rules, results obtained previously for the viscosity of pure gases have been extended to mixtures. Viscosity values ...

Natural gas viscosity is usually expected to increase both with pressure and temperature. A number of methods have been developed to calculate gas viscosity. The method of Lee, Gonzalez and Eakin is a simple relation which gives quite accurate results for typical natural gas mixtures with low non-hydrocarbon content. Lee, Gonzalez and Eakin (1966) presented the following correlation for the ...

Chat Online### Gas Viscosity - an overview | ScienceDirect Topics

Gas viscosity and density vary significantly with pressure and therefore the assumptions of Equation 6-76 are not satisfied for gas systems, i.e., compressible fluids. In order to develop the proper mathematical function for describing the flow of compressible fluids in the reservoir, the following two additional gas equations must be considered:

By application of the kinetic theory, with several simplifying assumptions, the previous equation of Buddenberg and the author has been modified to give a general equation for viscosity as a function of molecular weights and viscosities of the pure components of the mixture. Agreement of the equation with experimental data is demonstrated for a number of highly irregular binary gas systems and ...
