What is the best method for making major changes in the output rate of sprayers when droplet size is not critical?

When the focus is on making significant changes to the output rate of sprayers without concern for droplet size, adjusting the nozzle size is the most effective method. The nozzle is a critical component in determining how much product is expelled from the sprayer. Larger nozzle openings allow more liquid to pass through and increase the flow rate, directly impacting the output. This direct relationship between nozzle size and output enables applicators to achieve the desired flow rate needed for a specific application.

In contrast, modifying pressure can influence both the output rate and droplet size; however, it might not provide consistent control over the volume delivered. While changing the spray angle and application speed could potentially alter the effective coverage of the application, these methods do not directly relate to the volume output like nozzle size adjustments do. Therefore, for significant output rate changes in situations where droplet size isn't a concern, altering the nozzle size remains the most straightforward and effective choice.
