Ive seen slots like that at the top of a downcomer - in theory to break the surface tension of the bubbles so they collapse better before entering, without the bubbles we could use a much smaller tube - running bubble free water through it isnt a good test
While looking for a flow rate chart, I may have solved the length riddle too - there's a minimum length for a pipe to overcome the viscosity of the fluid vs the drag on the walls, check out the attached chart, the thing that would affect those numbers is the difference in viscosity of alc to water - alc is aprox 20% thicker so there would be a change in those numbers (by a different amount, beyond my paygrade) so all the way down to the next plate could make it more efficient.
