Taylor dispersion (axial dispersion coefficient)
Input(s)
R: Radius \((\mathrm{cm})\)
\(\boldsymbol{v}_{z}\): Average Velocity \((\mathrm{cm} / \mathrm{s})\)
\(\boldsymbol{D}_{\boldsymbol{A} \boldsymbol{B}}\): Diffusivity \(\left(\mathrm{cm}^{2} / \mathrm{s}\right)\)
Output(s)
K: Axial Dispersion Coefficient \(\left(\mathrm{cm}^{2} / \mathrm{s}\right)\)
Formula(s)
\[
\mathrm{K}=\frac{\left(\mathrm{R}^{2}\right) *\left(\mathrm{v}_{\mathrm{z}}^{2}\right)}{48 * \mathrm{D}_{\mathrm{AB}}}
\]
