Mass diffusivity - Wikipedia

2019-4-20 · Diffusivity, mass diffusivity or diffusion coefficient is a proportionality constant between the molar flux due to molecular diffusion and the gradient in the concentration of the species (or the driving force for diffusion). Diffusivity is encountered in Fick''s law and numerous other equations of physical chemistry. The diffusivity is

Diffusion Coefficients of Gases in Water - Engineering …

2019-4-12 · Diffusion coefficients for some common gases in water: (Gas–liquid diffusion coefficients are difficult to measure, and since the values below are from different sources and different measuring methods, there is some uncertainty about the values)

DIFFUSION COEFFICIENT - Thermopedia

Diffusion coefficient is the proportionality factor D in Fick''s law (see Diffusion) by which the mass of a substance dM diffusing in time dt through the surface dF normal to the diffusion direction is proportional to the concentration gradient grad c of this substance: dM = −D grad c dF dt. Hence, physically, the diffusion coefficient implies that the mass of the substance diffuses through a
