WebWeeping occurs when the vapor-side pressure drop across the tray deck is too low to support the liquid pool on the top side, so the liquid weeps through the holes. When the predicted dry-tray pressure drop falls below 12 mm H 2 O, weeping may become a problem. A good rule of thumb is that 20% weeping leads to a 10% loss in efﬁ ciency. http://content.alterra.wur.nl/internet/webdocs/ilri-publicaties/publicaties/pub20/pub20-h1.1.pdf
