Spray nozzle performance depends on which of the following?

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 shaped by several interacting factors that determine how well the spray covers the target, the size of the droplets, and the potential for drift. The nozzle type sets the spray pattern and the baseline droplet size and flow at a given pressure, so choosing the right nozzle is crucial for the job—some patterns cover broad areas with fine droplets, others use coarser droplets for different coverage. The distance to the target matters because droplets travel through the air and can drift or settle differently depending on how far away you are, affecting both coverage uniformity and off-target deposition. Operating pressure changes how much liquid is emitted and how finely it is atomized; higher pressure usually produces smaller droplets and more spray, while lower pressure reduces both flow and atomization. Since these factors all influence the outcome, all of them matter for nozzle performance.
