$2.-$ A packed absorber up to a height of$2\mathrm{.}4$ m$,$ it is used to reduce the concentration of AIn a gaseous stream of $6\mathrm{.}5$ to $1\%.$ An aqueous current, which initially contains $1\%$ of A$,$ is fed by the top of the tower. The tower is fed $20000$ ft$\text{'}/$h of the gas mixture at $60\backslash$deg F and $1$ atmosphere.Calculate: The amount of liquid current required per hour, if the tower works in parallel flow with a minimum Ls$/$Gs $=1\mathrm{.}5($Ls$/$Gs$)$ ratioHow much would the flow of the solvent be modified, if in reality the tower operated with countercurrent flows?Which of the $2$ fixes is more efficient, for the economy of the process?Calculate the global Kya mass transfer coefficient for the countercurrent operation.The balance data for this system are, on a solute$-$free basis:
