| (1) | {\nu}_{12}^{1/3} = x_1 \cdot \mu_1^{1/3} + x_2 \cdot \mu_2^{1/3} |
where
\mu_{12} | viscosity of fluid mixture | \mu_1 | viscosity of the 1st fluid component | \mu_2 | viscosity of the 2st fluid component |
x_1 | mole fraction of the 1st fluid component | x_2 | mole fraction of the 2nd fluid component |
The most straightforward generalization is provided by Lederer-Roegiers equation.
