Estimation of self diffusivity at high density
Input(s)
a: Concentration \(\left(\mathrm{g} \mathrm{mol}^{\mathrm{cm}} \mathrm{cm}^{3}\right)\)
Daa: Prediction of Self-Diffusivity \((\mathrm{g} \mathrm{mol} / \mathrm{cm} \mathrm{s})\)
cDaa \(_{\boldsymbol{r}}\): Reduced Diffusivity ( \(\mathrm{g} \mathrm{mol} / \mathrm{cm} \mathrm{s}\) )
Output(s)
\(\boldsymbol{c D a a}_{\boldsymbol{c}}\): Critical Diffusivity \((\mathrm{g} \mathrm{mol} / \mathrm{cm} \mathrm{s})\)
CDaa: Prediction of Self-Diffusivity \((\mathrm{g} \mathrm{mol} / \mathrm{cm} \mathrm{s})\)
Formula(s)
\[
\begin{aligned}
& \mathrm{cDaa}_{\mathrm{c}}=\frac{\mathrm{c} * \text { Daa }}{\mathrm{cDaa}_{\mathrm{r}}} \\
& \mathrm{CDaa}=\left(\mathrm{cDaa}_{\mathrm{c}}\right) *\left(\mathrm{cDaa}_{\mathrm{r}}\right)
\end{aligned}
\]
