Q$5)$ A: Estimate the packed column diameter and percentage of flooding for absorption of $S{O}_2$ from air using water as liquid. The feed will be $7500k\frac{g}{h}r$ of gas containing $3\%\frac{V}{V}SO,$ the slop of equilibrium line will be $27,$ using $1\mathrm{.}5$ in ceramic intalox saddle packing of $FP=55.$ The absorber operates at $25C,$ and $1\mathrm{.}5$ bar. Density of water $=1000k\frac{g}{m^3},$ viscosity of water $=0\mathrm{.}001N\frac{S}{m^2}.$ Using Fig. $(2)$ below.
