Effects of mechanically produced Capillary Waves on the Evaporation of Water through Monolayers

Abstract

THE extensive measurements¹ on the retardation of evaporation by monolayers conducted during the past decade at Columbia University have been restricted to static conditions to eliminate the erratic results arising from uncontrollable turbulence induced by a current of air passed over the surface of the water. We have extended these investigations by producing capillary waves of wave-length 0.5 cm, of frequency 60 c/s, and of amplitudes extending from 0.08 cm to 0.03 cm, by the action of a mechanical vibrator, that is, we have measured the effects of waves without the complication of wind.
