In class, we developed an expression for the height of an absorption tower in terms of HTUs

and NTUs based on a vapor phase driving force $($i$.$e$.,$ y$-$y$*).$ Here, you will extend the analysis to a

stripper to produce an expression for the tower height in terms of a liquid phase driving force $($i$.$e$.,$

x$-$x$*).[$Note: This choice is motivated by the fact that the solute is moving from liquid to vapor in

a stripping operation.$]$ I want you to develop equations for the operating line and the rate equation

of a stripper. The linear equilibrium line is simply rewritten as x$*=$ y$/$m$.$ Then, combine these to

find an expression for the height of a stripping tower in term of the HTU x and the NTU x $.$
