A packed countercurrent water-cooling tower using a gas flow rate of G = 1.356 kg dry air/s.m2 and water flow rate of L = 1.356 kg water/s.m2 to cool the water from TL2 = 43.3C to TL1 = 29.4C. The entering air at 29.4C has a wet bulb temperature of 23.9C. Mass transfer coefficient kGa is estimated as 1.20710-7 kg mol/s.m3.Pa and hLa/kGaMBP as 4.187104 J/kg.K. The tower is located at the sea level. Calculate the height of packed tower z and the minimum value of air glow rate, Gmin.
