A packed countercurrent water$-$cooling tower using air flow rate of $G=1\mathrm{.}4kg$ dry air $\frac{?}{s.m^2}$ and a water flow rate of $L=1\mathrm{.}4kg$ water $\frac{?}{s}*m^2$ is to cool the water from $44C$ to $30C.$ The entering air at $28C$ has a wet bulb temperature of $22C.$ The overall mass transfer coefficient $K_{G}a$ is estimated as $1\mathrm{.}5{10}^{-7}$kgmo$\frac{l}{s}.m^3.$ Pa$.$ The tower operates at a pressure of $1$atm.

Design a Cooling Tower that meets the requirements. Discuss other factors to consider for real design.
