What are the four characteristics of nozzles that are critical for selection?

The selection of nozzles in agricultural applications is critical due to their direct impact on the efficiency and effectiveness of spraying operations. The correct choice highlights four essential characteristics: orifice size, uniformity of spray, droplet size, and potential for drift.

Orifice size is vital as it determines the flow rate of the liquid being sprayed. A larger orifice can allow more liquid to pass through, which is suitable for certain applications, while a smaller orifice may be required for precision work.

Uniformity of spray is crucial for ensuring that the application is consistent across the target area. An uneven spray can lead to underdosing in some areas and overdosing in others, resulting in inefficient use of resources and potentially harming crops or the environment.

Droplet size affects how the liquid interacts with the target surfaces and the atmosphere. Smaller droplets can cover larger areas and penetrate dense canopies but may also increase the risk of drift, where droplets are carried away by wind to unintended areas. Managing droplet size is therefore essential for both efficacy and environmental safety.

Finally, potential for drift is a significant consideration as it relates to environmental impact and regulatory compliance. Low-drift nozzles are designed to minimize how far droplets can travel, reducing the risk of contamination
