In this paper the relationship between the droplet sizes and the frequency of their occurrences is investigated experimentally, giving consideration to the disintegration mechanisms of the jet. Fig. 1 shows the change of the frequency curve with increasing speed of rotation n. In this Fig., (a) and (b) correspond to the wavy jet and have two peaks of the frequency. The second lower peak moves towards the side of smaller size as the value of n increases. (d) 〜 (f) correspond to the partially sprayed jet. Since the jet is locally accompanied by the film-like disruptions, the number of the medium sized droplets is increased. In the spray the frequency curve becomes monotonous as shown in Fig. 4,and can be expressed by a formula dn/dx=ax^2e^<bx> where n is the number of droplets with diameter of x, and a and b are the constants. This formula is valid regardless the physical properties of liquid.
