Taylor dispersion (axial dispersion coefficient)

Input(s)

R: Radius (cm)(\mathrm{cm})

vz\boldsymbol{v}_{z}: Average Velocity (cm/s)(\mathrm{cm} / \mathrm{s})

DAB\boldsymbol{D}_{\boldsymbol{A} \boldsymbol{B}}: Diffusivity (cm2/s)\left(\mathrm{cm}^{2} / \mathrm{s}\right)

Output(s)

K: Axial Dispersion Coefficient (cm2/s)\left(\mathrm{cm}^{2} / \mathrm{s}\right)

Formula(s)

K=(R2)(vz2)48DAB\mathrm{K}=\frac{\left(\mathrm{R}^{2}\right) *\left(\mathrm{v}_{\mathrm{z}}^{2}\right)}{48 * \mathrm{D}_{\mathrm{AB}}}
