Diffusion Velocity
</dt>
1. The relative mean molecular velocity of a selected gas undergoing diffusion in
a gaseous atmosphere, commonly taken as a nitrogen (N2) atmosphere.
</dd>
The diffusion velocity is a molecular phenomenon and depends upon the
gaseous concentration as well as upon the pressure and temperature gradients
present.
</dd>
2. The velocity or speed with which a turbulent diffusion process proceeds
as evidenced by the motion of individual eddies. [[/a>|/a>
