Criterion for flooding which was found to be reproducible in packed columns has been described. Limiting velocities, holdup, and pressure drop at flooding have been experimentally determined for binary liquid systems in a countercurrent extraction column packed with raschig rings, Berl saddles, Lessing rings, and spheres. Generalized correlations have been suggested, with the experimental data taken into account along with, published data of other workers for the estimation of limiting velocities, holdup, and pressure drop at flooding.
