Example(1): (Adiabatic humidification and cooling of air). Air has to be humidified and cooled adiabatically in a honzontal spray chamber with recirculated water. The active part of the chamber is Im #2m #15 m long. Under the operating conditions, the coefficient of heat transfer is expected to be 1300 kcal/(hr)(m2)(°C). 200 m3/min of air at 60 °C and 1 atm pressure with a humidity of 0.018 kg water/kg dry air is to be blown through the spray chamber. Calculate the following (a) the temperature and hunudity of the exit air (b) make-up water to be supplied, windage and blow down are neglected (c) the expected gas-phase mass transfer coefficient, kya (d) the temperature and humidity of the exit air if an identical spray chamber is added in series with the existing one O
