Gas A available in the air is to be absorbed in fresh water using a packed column. Feed enters at $1\mathrm{.}2k\frac{g}{s}$ with $0\mathrm{.}1$mol fraction of gas A$.$ The exit gas stream consists of $0\mathrm{.}001$mol fraction of gas A$.$ The exit water stream contains $0\mathrm{.}003$ mole fraction of gas A$.$ Design the packed column for the following data: Molecular weight of gas A and air is $20$ and $29\frac{g}{g}$mol, respectively. The slope of the equilibrium line is $14.$ Berl saddle packing of $25mm$ is used. The pressure drop and column temperature are $8mm{H}_2\frac{O}{m}$ packing and $25C,$ respectively. Properties at operating temperature: ${}_v=9k\frac{g}{m^3},{}_v=1000k\frac{g}{m^3},{}_4={10}^{-3}N\frac{s}{m^2},{}_v=1\mathrm{.}5{10}^{-5}N\frac{s}{m^2},D_1=2{10}^{-9}\frac{m^2}{s},D_v=2{10}^{-5}\frac{m^2}{s},f_1=f_2=f_3=1?$
