Diffusion Equation: Fick''s Laws of Diffusion

where M i is the relative molar mass (kg mol-1) of species i.. The diffusive mass flux of each species is, in turn, expressed based on the gradients of the mole or mass fractions, using multi-component diffusion coefficients D ik.These are symmetric, so that an n-component system requires n(n-1)/2 independent coefficients to parameterize the rate of diffusion of its components.

Diffusion Coefficient Definition - COMSOL

A typical diffusion coefficient for a molecule in the gas phase is in the range of 10-6 to 10-5 m 2 /s. By contrast, diffusion for molecules dissolved in liquids is far slower. From the above definition, the diffusion coefficient has units of area per time (m 2 s-1, or m 2 /s in SI units). Multi-Component Diffusion.

What''s a Better Sampling Methodology for a Toxic …

2019-4-16 · Definitions. There are two prominent sampling methods used in gas detection: Sample draw and passive diffusion. A sample draw system uses a pump to draw sample back into the instrument, where it enters the sensor for analysis, and is then exhausted to the atmosphere or vent line.. Gas detection instruments with passive diffusion sensors do not use a pump to pull the sample to the sensor.
