$1500\frac{kg}{hr}$ of flue gas having $10$ mote$\%$ of sulfur

dioxide is to be absorbed using pure water and

recover $97\%$ of $S{O}_2$ in water. The operatingconditions

of absorber is $1$atm and $30C.$ The average molecular weight

of flue gas is $32\mathrm{.}3\frac{kg}{\text{k}\text{m}\text{o}\text{l}}.$ The absorber is packed

with $25mm$ Raschig rings. Further data given is

$k_{x}a=1\mathrm{.}25\frac{\text{k}\text{m}\text{o}\text{l}}{m^{3}s}$;$,k_{y}a=0\mathrm{.}75$ kmo$\frac{l}{m^3}s$

Determine minimum liquid flow rate, actual flow vate

and determine the height of the tower. The equilibrium

data is as below.
