In this paper, the effects of the surface tension and the viscosity of liquid on the spray angle and the mean diameter of dop, were investigeted. The spray angle can be arranged in the main features by introducing the Reynolds' number of the swirl chamber. According to the results, we obsained a general empirical formula for the spray angle. The mean diameter of drop is directly proportional to the fourth root of the surface tension for the non-viscous liquid, The general empirical formula for the mean diamter of drop was induced from the results of the measurements, addition to that in the "Supplement of the 2nd Report". We can neglect the effect of the viscosity on the size of drop, when the dimensionless number (ρν^2/σt_0)<0.015 as its effect is smaller than 1%.
