Distillation column flooding $-E.$ Following the notation of Section $4\mathrm{.}7,$ a bubble$-$cap distillation column has values $H=1ft,C_D=0\mathrm{.}62,D=0\mathrm{.}1ft,W=2ft,$ and $=0\mathrm{.}1ft.$ If flooding is just to be avoided, what is the maximum liquid flow rate $L(f\frac{t^3}{s})$ that can be accommodated? What are then the liquid velocity through the opening at the bottom of a downcomer and the height of the liquid above the weir?
