A. Distance
- Distance of max. trajectory height from sprinkler nozzle.
B. height
- Elevation of max. trajectory height above ground.
Trajectory height above sprinkler nozzle
The maximum trajectory height above the sprinkler nozzle is relevant in the following cases:
•
When sprinklers are used under the canopy to prevent wetting the foliage.
•
When sprinklers are used in a net-house or inside a roofed structure such as a glasshouse, to prevent
wetting the net or the ceiling.
