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)

Uniform coverage along a spray boom comes from using nozzle tips that produce a consistent, evenly distributed spray pattern across their spray angle. A regular flat fan tip provides a steady, flat spray that spreads evenly across the width it covers, so when you space these tips evenly, the overlap creates uniform coverage across the boom. A whirl chamber tip also distributes spray in a uniform way across its spray arc, helping maintain even application when tips are placed at equal intervals. Raindrop nozzles tend to produce more variable droplet sizes and patterns, which can lead to gaps or overly dense patches if the tips are spaced evenly. Using either regular flat fan or whirl chamber tips—ideally both on a correctly spaced boom—gives reliable, uniform coverage, which is why that combination is the best choice.
