Which method can be used to adjust a sprayer's output?

Adjusting a sprayer's output is primarily done by changing the pressure. The pressure directly influences the flow rate of the liquid being sprayed, which in turn affects the volume of the chemical application. Higher pressure generally increases the output of the sprayer and allows for finer droplets, while lower pressure reduces the output and can result in larger droplets. This method is commonly used by applicators to achieve the desired coverage and application rate for pest control or fertilization.

While changing the product may alter the effectiveness or compatibility of the application, it does not directly impact the sprayer’s output in terms of flow rate or droplet size. The distance from the target can also affect the efficacy of application but does not adjust the sprayer's flow output itself. Lastly, changing the sprayer's location might be necessary for effective treatment but is unrelated to the output adjustment mechanism of the sprayer.
