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)

$$ \mathrm{K}=\frac{\left(\mathrm{R}^{2}\right) *\left(\mathrm{v}_{\mathrm{z}}^{2}\right)}{48 * \mathrm{D}_{\mathrm{AB}}} $$
