The fliuid on the plate below.
So long as the top of the hole is covered, by setting the downcomer height on the next plate, it will form a fluid lock. Vapor is then forced through the holes.
BT1, you might have to shorten the "foot" a little, as you dont want to have to set the downcomers in the next plate too high.
But the main trick is in the J cup on the bottom plate. Without that, it wont work. It provides the fluid lock the rest of the plates need.
If you think of a weir plate design, there is no cups.
