$29\mathrm{.}18$ Wastewater containing solute $A$ at a concentration of $1\mathrm{.}0{10}^{-3}$gmo$\frac{l}{m^3}$ enters an open tank at a volumetric flow rate of $0\mathrm{.}2\frac{m^3}{m}in,$ and exits at the same rate. Solute A transfers from the wastewater in the open tank to the surrounding air which is essentially free of the solute. The total system pressure is $1\mathrm{.}0$atm. The diameter of the cylindrical tank is $4m,$ and the depth of the liquid in the tank is $1\mathrm{.}0m.$ At these conditions the individual liquid$-$film mass$-$transfer coefficient, $k_L,$ is $5{10}^{-4}$kgmo$\frac{l}{m^2}*s*(kgmo\frac{l}{m^3})$ and the individual gas$-$film mass$-$transfer coefficient, $k_G$ is $0\mathrm{.}01$kgmo$\frac{l}{m^2}*s*atm.$ The concentrations are in the Henry's law region where $p_{Ai}=H_{\text{c}\text{A}\text{i}}$ with $H$ equal to $10a\frac{t}{m}\frac{?}{(kgmo\frac{l}{m^3})}.$ What is the percent resistance to mass transfer in the liquid film?
