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)

$$ \mathrm{D}_{\mathrm{AB}}=\frac{\mathrm{K} * \mathrm{~T}}{6 * \pi * \mu_{\mathrm{B}} * \mathrm{R}_{\mathrm{A}}} $$
