Oil is cooled by spraying a mist of the hot liquid through cool air at T[infinity]=27oC. Two droplets, each of diameter D =100 μm and temperature 250oC, suddenly collide and coalesce into a single droplet. Determine the heat transfer rate from the oil to the air before and after coalescence of the droplets. The velocity of the droplets is V=5 m/s.
