What type of stream does the Bresnan nozzle produce?

The Bresnan nozzle is designed to produce a broken stream of water, which is particularly effective in fire suppression situations. A broken stream creates a wide distribution of water droplets, which enhances the cooling effect and helps disperse heat effectively. This type of stream also allows for better penetration into a fire, especially in confined or congested spaces, by disrupting the airflow and smothering the fire.

In contrast, a smooth stream is more focused and is typically used for longer-range applications, while a fog stream creates a mist that is ideal for protective purposes or when a large area needs to be covered. A solid stream, on the other hand, delivers a direct and uninterrupted flow of water, which may not be as effective in certain firefighting scenarios as the broken stream provided by the Bresnan nozzle. The unique design and operation of the Bresnan nozzle allow it to effectively combat various fire conditions, making the broken stream the ideal choice in many firefighting environments.
