Oil is cooled by spraying a mist of the hot liquid through cool air at T∞=27∘C. Two droplets, each of diameter D=130μm and temperature 250∘C, suddenly collide and coalesce into a single droplet. Determine the heat transfer rate, in W, from the oil to the air before and after coalescence of the droplets. The velocity of the droplets is V=5 m/s. qbefore =qafter =WW
