What term refers to the range in droplet size that a spray nozzle produces?

• A. Droplet Spectrum
• B. Even flat-fan pattern
• C. Effective Swath Width
• D. Environment

Answer: (A)

The main idea is that nozzles emit a range of droplet sizes rather than a single size. This distribution across sizes is called the droplet spectrum. It describes how much spray volume falls into each size category—from fine droplets that cover surfaces well but drift easily, to larger droplets that deposit more reliably but may provide less uniform coverage. Knowing the droplet spectrum helps you balance coverage and drift potential when selecting nozzles and pressure settings. The other terms describe different concepts: an even flat-fan pattern refers to the spray’s shape and uniformity, not the size distribution; effective swath width is about how wide the spray travels on the ground; and environment involves external factors like wind and temperature that affect application performance.
