A distillation column is a process unit in which a feed mixture is separated by multiple vaporizations and condensations to form two or more product streams. The overhead product stream is rich in the most volatile components of the feed mixture $($the ones that vaporize most readily$),$ and the bottom product stream is rich in the least volatile components. The following flowchart shows a distillation column with two feed streams and three product streams. Suppose values are given for $=1950\mathrm{.}0$ kg$/$h and x$2$A $=0\mathrm{.}550.$ Solve for the remaining unknowns.
