In spray equipment, which component primarily controls the rate and pattern of the spray?

• A. Nozzle
• B. Orifice
• C. Nutlet
• D. Nymph

Answer: (A)

The nozzle is what primarily controls how much spray comes out and how it is distributed. The shape and design of the nozzle determine the spray pattern—whether it exits as a flat fan, a hollow cone, or a solid cone—and, at a given pressure, the size of the outlet (the orifice) sets the flow rate. In practice, selecting the right nozzle type and size lets you tailor both coverage and droplet size, which is essential for even application and drift control. The orifice is part of the nozzle and influences flow, but it isn’t a separate control that determines pattern on its own. The other terms listed aren’t components used to manage spray in typical equipment.
