# Abstract:

An experimental study was made of the drop-size distributions obtained on injecting a liquid solution composed of, by weight, 15 2, 4-dihydroxy-benzophenone in 85 bis 2-ethylhexyl hydrogen phosphite into nitrogen gas streams at sonic velocity. The liquid solution was introduced into the gas stream through a single injector and through tripled injectors. Variations were imposed in the flow rates of both liquid and gas, and in the temperature of the gas. The collected aerosol droplets were sized, counted, and described mathematically using a modified form of the logarithm log- probability distribution function. The parameters of the distribution function are shown to vary directly with the flow rate ratio of liquid to gas. Equations were determined showing the variance of the two logprobability parameters. These equations were developed using the same form as that of the Nukiyama-Tanasawa relationship. This extension of the Nukiyama-Tanasawa equation enables predicting the particle-size distribution rather than just a mean diameter of the distribution.
