Here bulk flow represents the total flow of component (i) multiplied by it's mole fraction that is participating in diffusion and diffusion represents the component (i) which doesn't diffuse (I mean which doesn't participate) into other component say J is diffusion.

How it describe bulk flow? Please explain.

What is bulk flow?

I think this law only describes about diffusion.

Na = -D*dCa/dy*Ct/Cb is Steafan's law.

Where Na is molar flux of a.

Ca is concentration of A.

Ct is total concentration.

Cb is concentration of B.

D is diffusion.

In diffusion Stefan's pipe is used, where a horizontal and vertical pipe are attached.
