Webb11 apr. 2024 · where ε is porosity, η is the flow viscosity, d is the diameter of fiber, Δp is the pressure difference, L is the thickness of sample and k D is Davies’ permeability coefficient. It can be seen from equation ( 3 ) that the permeability is not merely linearly related to porosity, but also associated with many other complex parameters. WebbThe permeability coefficient is the product of gas flux and membrane thickness divided by the pressure difference across the membrane. Gas selectivity is the ratio of permeability coefficients of two gases (R A/B) P A/P B), where P A is the permeability of the more permeable gas and P B is the permeability of the less permeable gas in the ...
