What is the thermal dynamic effect when the nozzle tip is positioned below the boom?

Positioning the nozzle tip below the boom creates a dynamic effect that influences how the spray material is dispersed and collected. When the nozzle is situated lower than the boom, the spray can be subjected to various forces that may lead to a reduction in the amount of spray material that is deposited on the intended target area.

This positioning can cause the spray to spread more widely and may not aggregate correctly, leading to a loss of material that would otherwise make contact with the crop or field. Effectively, this configuration can result in the spray falling off or missing the target altogether, thus leading to a decreased deposition efficiency.

The choice provided captures this concept accurately, emphasizing the impact on spray material deposition.
