Spray nozzle performance depends on which of the following?

• A. All of the above
• B. Nozzle type
• C. Distance to target
• D. Operating pressure

Answer: (A)

Spray nozzle performance is determined by a combination of nozzle type, distance to target, and operating pressure. The nozzle type sets the spray pattern, droplet size, and flow characteristics, which directly affect how evenly the target is covered. The distance to the target changes where those droplets land and how much energy they have on impact, impacting coverage uniformity and drift risk. The operating pressure controls the flow rate and atomization: higher pressure produces finer droplets and longer reach but can increase drift, while lower pressure yields larger droplets and reduced reach. Because all three factors influence coverage, reach, and droplet behavior, considering them together explains why “all of the above” is the best answer. To optimize performance, choose an appropriate nozzle type, maintain proper pressure, and position the nozzle at the right distance from the target.
