In the present paper, an attempt is made to study the evaporation of a single liquid droplet hanged by a quartz fiber, by means of recording on motion pictures. The evaporation of twelve pure liquids, five blends and petroleum fuels namely, water, methylalcohol, ethylalcohol, benzene, toluene, nitrobenzene, cyclohexane, n-hexane, n-heptane, iso-octane, cetane, α-methylnaphthalene, water-methylalcohol blend, motor gasoline, kerosine, diesel light oil. and heavy oil, was studied. As the derivative of the square of the diameter of the droplet with respect to time is constant value for pure liquid and it is satisfactorily proved that the life of the droplet is proportial to the square of its initial diameter for blends or petroleum fuels, it may be convenient to represent the rate of evaporation velocity by that constant which may be called the "coefficient of evaporation velocity of droplet." The results were compared with the theory^<(9)>, and satisfactory agreements were obtained between them.
