What is a primary function of spray nozzles?

The primary function of spray nozzles is to regulate the flow of liquid and atomize it. Spray nozzles are designed to control how a liquid is dispersed, allowing it to break into smaller droplets, which is critical for applications like spraying pesticides, paints, or cleaning solutions. Atomization enhances the coverage area and efficiency of the liquid being applied, ensuring a more uniform distribution. This is essential in various industries, including agriculture, automotive, and manufacturing, where precise delivery of materials is necessary for optimal results.

The other functions listed, such as preventing evaporation, heating the liquid, or increasing viscosity, do not fall within the primary purposes of spray nozzles. Instead, these functionalities are typically handled by different mechanisms or equipment, emphasizing the specific role that nozzles play in fluid dynamics and application processes.
