Which component of the nozzle determines the flow rate and droplet pattern?

The nozzle size is the critical component that influences the flow rate and droplet pattern of the spray. A larger nozzle size typically allows for a higher flow rate, leading to a greater volume of liquid being dispensed per unit of time. Additionally, the size of the nozzle affects the formation of droplets; smaller nozzles tend to create finer droplets, while larger nozzles produce coarser droplets.

By manipulating the nozzle size, applicators can tailor the spray characteristics to better suit specific pest control needs, ensuring effective coverage and minimizing drift. This capacity is essential for achieving desired outcomes in pest management and for adhering to regulations regarding pesticide application.

While other factors, like nozzle angle and design, influence the direction and distribution of the spray, it is the nozzle size that primarily determines how much product is being applied and the resultant droplet formation, making it crucial for effective application.
