A steam of air at 500°C and 835 torr with a dew point of 30°C flowing at a rate of 1515 L/s is to be cooled in a spray cooler. A fine mist of liquid water at 25°C is sprayed into the hot air at a rate of 110.0 g/s and evaporates completely. The cooled air emerges at 1 atm.a. Calculate the final temperature of of the emerging air steam, assuming that the process isadiabatic. (Suggestion: drive expressions for the enthalphies of dry air and water at the outlet air temperature, substitute them into the energy balance, and use a spreadsheet to solve the resultin fourth order polynomial equation. )B. At what rate (kW) is heat transferred from the hot air feed stream in the spray cooler? What becomes of this heat?c. In a few sentences, explain how this process works in terms that a high school senior could understand. Incorporate the results of parts (a) and (b) in your explaination.
