WebVISCOSITY OF GASEQUS MIXTURES By Thomas A. Elavidson' ABSTRACT The Bureau of Mines Helium Field Operations has developed a simple and accurate method for calculating the viscosity of gas mixtures. Only the composition of the mixture and the molecular weights and viscosities of the pure components in the mixture are required. Web11 de mar. de 2024 · The most commonly used unit of viscosity is the centipoise, which is related to other units as follows: 1 c p = 0.01 poise = 0.000672 lbm/ft-s = 0.001 Pa-s. Natural gas viscosity is usually expected to increase both with pressure and temperature. A number of methods have been developed to calculate gas viscosity.
