Diffusion-controlled evaporation of aerosol droplets in an ambient gas is important in various engineering and scientific fields, such as premixing air and fuel, ink-jet printing, spraying of pesticides, biochemical assays, and atmospheric pollution. For isothermal, quasi-steady evaporation, Maxwell [1], showed that the time rate of change of the droplet radius is given by
