Forced Convection Mass Transfer Bird, Stewart, and Lightfoot. John Wiley and Sons. This section of the text deals with an illustration of forced-convection mass transfer. The conditions under which the viscous flow and diffusion occur allow the velocity field to be viturally unaffected by diffusion. B. This makes the viscosities not change appreciably.
Diffusion takes place very slowly in the film.
The penetration distance will be small relative to the thickness of the film. Using Maple V, we hope to setup the equations that are indicative of the process described above. An essential command at the start of each new Maple worksheet. We start by first defining Az and Ax. Az and Ax are cross-sectional areas.
