What is the result of rotating a round boom with the nozzle tip positioned below it?

When a round boom is rotated with the nozzle tip positioned below it, it primarily reduces the spray material released in a low-pressure area. This phenomenon occurs because the nozzle is at a position where it is not effectively delivering the pesticide to the intended area, which can result from the dynamics of how the spray interacts with the air. When the nozzle is below the boom, the spray may not distribute evenly, and a considerable amount of material may escape into areas where it is less effective or even lost entirely.

This method can create a situation where the primary pressure dynamics favor a high-pressure area primarily in the direct line of the spray nozzle while the regions farther from that line experience lower pressure and less coverage. Consequently, reducing the effective amount of pesticide deposited leads to concerns about application effectiveness and target coverage.

Moreover, while rotating the boom may have implications for spray pressure and pattern, the immediate result of having the nozzle tip below the level of the boom primarily impacts the volume of spray material effectively released into the target area, confirming the validity of this choice.
