Notes:
A generalized correlation is presented for the backmix ratio in multistage agitated contactors. The backmix ratio is shown to be a function of the ratio of impeller tip speed to superficial flow velocity, and of the column configuration and impeller design. For single-phase flow and for the continuous phase in two-phase flow, the following expression is recommended: \documentclass{article}\pagestyle{empty}\begin{document}$$\alpha = 0.0098\left[ {\varepsilon \frac{{ND}}{u}\left( {\frac{{D^2 a}}{{THA}}} \right)^{1/2} } \right]^{1.2}$$\end{document}
