Theory of diffusion in colloidal suspensions

Input(s)

K: Molar Transfer Coefficient (mol/scm2)\left(\mathrm{mol} / \mathrm{s} \mathrm{cm}^{2}\right)

T\mathrm{T}: Temperature (K)(\mathrm{K})

μB\mu_{B}: Viscosity (cP)(\mathrm{cP})

RA\boldsymbol{R}_{A}: Radius (cm)(\mathrm{cm})

Output(s)

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

Formula(s)

DAB=K T6πμBRA\mathrm{D}_{\mathrm{AB}}=\frac{\mathrm{K} * \mathrm{~T}}{6 * \pi * \mu_{\mathrm{B}} * \mathrm{R}_{\mathrm{A}}}
