The distance between nozzles should be _______ the boom height.

The distance between nozzles should be _______ the boom height.

• A. Twice
• B. One-half
• C. The same as
• D. Three quarters

Answer: (C)

Uniform spray coverage comes from overlapping the patterns from adjacent nozzles at the target. When the spacing between nozzles is equal to the boom height above the ground, the spray swaths from neighboring nozzles meet and fill in the area evenly, giving consistent coverage. If the nozzles are spaced farther apart than the height, gaps can appear in the treated area; if they’re spaced closer than the height, there’s more overlap and potential waste or drift. This relationship helps maintain a uniform application assuming a typical nozzle pattern and spray angle.
