Which nozzle tips are used evenly spaced on booms?

• A. Raindrop
• B. Regular flat fan
• C. Regular flat fan and Whirl chamber
• D. Whirl chamber

Answer: (C)

When you place nozzle tips evenly along a boom, the goal is to create overlapping spray patterns so every part of the target band receives uniform coverage. Regular flat fan nozzles are designed to spread a consistent, fan-shaped spray with a defined spray angle. If you space these tips evenly, their individual patterns overlap smoothly, producing uniform deposition across the boom’s width. Whirl chamber nozzles also deliver a predictable pattern that maintains even coverage when arranged at equal intervals, making them suitable for booms as well. Raindrop nozzles tend to produce larger, less predictable droplets whose coverage can vary with pressure and distance, leading to gaps or nonuniform deposition when spaced evenly. Because regular flat fan and whirl chamber nozzles provide reliable, uniform overlap when evenly spaced, they are the best match for booms.
