What is the spray angle and flow rate of a nozzle described as?

The correct answer describes a nozzle designed to deliver a precise pattern and flow rate that is particularly effective for certain agricultural applications. A spray angle of 80 degrees is broad enough to cover a wide area while still providing sufficient droplet size and distribution for effective pest control. This angle allows for adequate coverage of crops without excessive overlap, which can lead to waste of the pesticide or herbicide being applied.

The flow rate of 0.4 gallons per minute is moderate, aligning well with the needs of many spraying applications. This flow rate is not too high, which reduces the risk of drift—a critical consideration when applying chemicals in agricultural settings, especially in proximity to sensitive crops or non-target areas. The combination of an 80-degree spray angle and this specific flow rate suggests that the nozzle is optimized for delivering chemical solutions at an efficient coverage rate while minimizing potential environmental impacts.

Other choices present different combinations of spray angles and flow rates that may not offer the same balance of coverage and precision suitable for effective pest management.
