The reduction in distillation tray efficiency caused by uniform weeping of liquid from the tray has been calculated. Numerical results are presented for all three Lewis cases over the range of variables of interest to tray designers. Analytical equations are given for Lewis' cases 2 and 3 for plug flow of liquid on the tray.
