A cooling tower is to be designed to cool water from $50C$ to $30C$ by counter current contact with air of dry bulb temperature $30C$ and wet bulb temperalure $25C.$ The water flow rate is $5500k\frac{g^2}{l}{m}^2.$ Air rate is $1\mathrm{.}25$ times the minimum. Overall mass transfer coeflicient is $K_{y^{\text{'}}}^{\text{h}\text{a}\text{t}(a)}=2500k\frac{g}{m}{m}^{\text{'}}($tie$-$lines are vertical lines$).$ Determine the packing height required. The equilibrium data is provided below. The equilibrium graph for equilibrium enthalpy$-$temperature cturve is also attached with the question paper, you are free to use the graph paper. Attach the used graph with your answer script
