Theory of diffusion in colloidal suspensions
Input(s)
K: Molar Transfer Coefficient \(\left(\mathrm{mol} / \mathrm{s} \mathrm{cm}^{2}\right)\)
\(\mathrm{T}\): Temperature \((\mathrm{K})\)
\(\mu_{B}\): Viscosity \((\mathrm{cP})\)
\(\boldsymbol{R}_{A}\): Radius \((\mathrm{cm})\)
Output(s)
\(\boldsymbol{D}_{\boldsymbol{A} \boldsymbol{B}}\): Diffusivity \(\left(\mathrm{cm}^{2} / \mathrm{s}\right)\)
Formula(s)
\[
\mathrm{D}_{\mathrm{AB}}=\frac{\mathrm{K} * \mathrm{~T}}{6 * \pi * \mu_{\mathrm{B}} * \mathrm{R}_{\mathrm{A}}}
\]
