Oxygen Transfer From Falling Water Droplets

Overall oxygen transfer coefficients are obtained for deaerated water droplets falling freely through the atmosphere with and without 50 ppm. of a synthetic detergent. Drop distances ranged from 0 to 13 ft, and droplet surface areas varied from 0.47 to 0.55 cm2. Transfer coefficients are found to decrease somewhat with increasing droplet size, becoming independent of droplet size above 6.0 ppm of D.O. With detergent present, the coefficients are...
