Diffusion Coefficient (DAB) in Mass Transfer Operations Formulas

The Diffusion Coefficient (DAB) is the amount of a particular substance that diffuses across a unit area in 1 second under the influence of a gradient of one unit. And is denoted by DAB. Diffusion Coefficient (DAB) is usually measured using the Square Meter Per Second for Diffusivity. Note that the value of Diffusion Coefficient (DAB) is always positive.
