Studies on the Sprinkler-Head (Part 1)

On the Trial Manufacture of Arm-type Sprinkler-heads and the Distribution of Water

Abstract

1. We have intended to design some sprinkler-heads which are simpler in the construction and easier in handling, and which sprinkle water more uniformely over the entire area of the irrigation, in comparison with other types of head.
The authors named these sprinkler-heads “ARM-TYPE.”
2. The effects of the Arm-type sprinkler-heads on the distribution of water over the area of the irrigation were investigated on the water pressure, nozzle diameter and the angle of the inclination of the sprinkler arm.
3. In judgement, VA-3 type head is the best of all, VL type the next and followed by V A-1 and VA-2 type.
