Tests
- Distribution curve: the objective of this test is to determine the sprinkler’s precipitation pattern as a function of distance, measured along a specific section (radius) or line of the coverage area.
- Distribution curve: the objective of this test is to determine the sprinkler’s precipitation pattern as a function of distance, measured along a specific section (radius) or line of the coverage area.
- Droplet size: the objective is to characterise the distribution of droplet sizes produced by an irrigation sprinkler.
- Rotation speed: the objective is to determine the number of revolutions per minute of the sprinkler operating at nominal pressure.
- Trajectory height: the objective is to determine the peak height of the water trajectory above the sprinkler nozzle when operating at test nominal pressure.
- Distribution uniformity for different irrigation patterns: the objective of this study is to characterise water application uniformity from sprinklers using full-grid data, through a coefficient that uses an arbitrary definition of the lowest 25% as the critical area.
- Sprinkler durability: the objective is to assess how the sprinkler’s functional characteristics vary over time.
