A. Experiments were conducted in order to measure the diameter of the water drops falling down from the inside of the shijoka, and as a result the following relationship was made clear:
1. Diameter of water drops
The following experimental formula was obtained in connection with the relationship between the radius (r) of the water drops and that (R1 and R2) of the trace of the water drops marked on the filterpaper of eosin and the glass plate coated with magnesium oxide:
(1) Eosin paper
r=399.80+0.121R1-337.36l-0.0005R1
(2) Magnesium oxide plate
r=-1.70+0.68R2
2. Form of water drops
The following experimental formula was obtained in connection with the relationship between the radius (r) and the transforming rate of the water drops (b/a: b: height of the drops, a: horizontal maximum length of the drops):
b/a=1.015-0.017r-0.013r2
B. The water drops with the radius which is less than 0.02cm.occupy 50 percent of all the drops falling down from the Shijoke.
