The recommended nozzle pressure for 2-1/2" hand lines with solid bore tips is what pressure?

The recommended nozzle pressure for 2-1/2" hand lines with solid bore tips is 50 psi. This pressure is established to ensure optimal performance of the nozzle, allowing for effective reach and penetration of water onto a fire. A solid bore nozzle is designed to produce a straight stream of water, maximizing both reach and striking power, which is essential in fire suppression activities.

By setting the nozzle pressure at 50 psi, fire operators can achieve a balance between flow rate and stream velocity. This is particularly important for larger hand lines, where maintaining adequate pressure ensures that the water is delivered effectively to extinguish fires while also allowing the operator to manage the nozzle with appropriate control and stability.

Utilizing this recommended nozzle pressure supports a standard approach across fire departments, ensuring that personnel can work cohesively during operations, especially in challenging scenarios. Understanding this standard helps operators prepare for consistent firefighting performance and enhances the overall effectiveness of their firefighting efforts.
