Axial Dispersion in Laminar Pipe Flow

To simplify the extrachon of reaction rate parameters from experimental data, the tube was designed so that the ID axial dispersion model would apply over the enhre range of expected residence hmes. This model is given in Eq. (11)  

For reactor channel aspect ratios (L/D) that exceed 10, the boundary defining the limit of applicability of the axial dispersion model is approximated by Eq. (13) 

Equation (13) defines the maximum flow rate (minimum residence time) in a given tube that can be modeled using the 1D axial dispersion model.
