What is Stefan's law ?

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

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.

I think this law only describes about diffusion.

What is bulk flow?

How it describe bulk flow? Please explain.

Ramana said: (Aug 12, 2018)  
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.
