Abstract

Calculations, based on Fuchs’ (1959) formula, of evaporation rates of water droplets freely falling through air are compared with those of water‐based pesticide droplets measured by Dennison and Wedding (1984) in a wind tunnel. Results indicate that calculations of evaporation rates of water droplets, are not significantly different from measurements of that of water‐based pesticide droplets under conditions of 20 °C and 20% relative humidity, but different under other measurement conditions.
