At which nozzle pressure is a smooth-bore nozzle designed to operate?

A smooth-bore nozzle is designed to operate at a specific nozzle pressure, typically around 50 psi. This nozzle type is favored for its ability to produce a solid stream with minimal turbulence, which is advantageous for effective water delivery and penetration into fire conditions. The 50 psi operating pressure ensures optimal performance, allowing for a good balance between reach and volume of water delivered.

Using this nozzle at its designed pressure helps maintain the operational integrity of the nozzle, ensuring that firefighters can effectively combat fires without compromising safety or performance. Higher pressures, such as 75 psi or more, may create unnecessary strain on the nozzle and could lead to excessive wear or potential failure. Thus, understanding the intended operational pressure is crucial for effective firefighting and safety.
