Abstract
The evaporation rates of small (radius 3–9 μ), freely failing water droplets were determined. The droplets, produced in a diffusion cloud chamber, were allowed to fall through air of known relative humidity (95–99%) and at three ambient temperatures (25, 30 and 35C) in. a vertical drift tube. The rates of evaporation were ascertained by recording the drop positions on film at fixed time intervals. The results are compared with several existing theories, and are found to lie between the formulation of Kinzer and Gunn and the quasi-stationary theory based on Maxwell's equation.
