Which of the following factors governs sprayer output?

• A. Number of nozzles
• B. Color of nozzle tips
• C. Brand of pesticide
• D. Operator's height

Answer: (A)

Sprayer output is determined by the total liquid flow the sprayer can deliver, which depends on how many nozzles are spraying at once. If each nozzle delivers a certain flow rate and the pressure and travel speed stay the same, adding more nozzles increases the overall volume applied per unit time, raising the output. The color of nozzle tips doesn’t change how much fluid comes out; it usually signals pattern or size, not volume. The brand of pesticide doesn’t affect the sprayer’s discharge rate, and a person’s height doesn’t alter the flow from the sprayer. So, among these factors, the number of nozzles most directly governs output, though in practice nozzle size, pressure, and speed also influence the final application rate.
