Summary The distribution problem is, in the first instance, a problem of surface energy of the formed drops. It is shown that the distribution of drop size from atomization follows statistical laws. The formulae derived with methods of the classical statistics permit calculation of the distribution-curve with the aid of measurable parameters for certain types of atomizers, i. e. relative velocity between liquid and air, surface tension, viscosity of liquid and air, and air density. The formulae for the distribution of drops, surface and volume of the drops contain two parameters, the maximum drop diameter and the exchange-factor. The former can be calculated by aid of a stability criterion on a single drop, as it will be shown in another article. The exchange-factor, however, which is of similar signification as the temperature inMaxwell's distribution of molecul velocities in perfect gases, depends on the type of atomizer. The new formulae describe the experimental data much better than all known functions (e.g. Rosin-Rammler). However, for their use, which allows the knowledge of distribution curves without experiments, it is necessary to know the formula of maximum drop diameter and to make an analysis of the operation of the atomizer-type, permitting the establishment of the exchange factor.
