A $2\mathrm{.}5-$in$-$ID wetted wall column is being used to strip $C{O}_2$ from an aqueous solution by an air stream at $1\mathrm{.}0$

$\frac{m}{s}.$ At one point in the column, the concentration of $C{O}_2$ in the air stream is $1\mathrm{.}25$ mole percent. At the

same point in the column, the concentration of $C{O}_2$ in the water is $0\mathrm{.}8$ mole percent. Determine the gas$-$

mass$-$transfer coefficient mole$/$atm$-m^2-s)$ and the mass flux at the point in the column. The column

is operated at $10$atm and $25C.$ The Henry's constant of $C{O}_2$ in water at $25C$ is $1\mathrm{.}64{10}^{3}at\frac{m}{m}$ole

fraction $C{O}_2$ in solution. For correlations, refer to the table given in the lecture $($taken from CHE handbook$).$
