What is the common GPM output at 50 psi for a Metro 2 Smoothbore tip?

The common GPM output at 50 psi for a Metro 2 Smoothbore tip is typically 250 GPM. This figure is derived from the design characteristics of the smoothbore nozzle, specifically intended for delivering a consistent flow rate under standard operating pressures.

At 50 psi, the smoothbore nozzle is calibrated to optimize both the intensity of the stream and the reach, which is crucial for effective fire suppression tactics. The 250 GPM output reflects a balance between adequate water delivery for extinguishing fires and maintaining manageable flow and control for the firefighter operating the hose.

Understanding these flow rates is fundamental for fire engineers and responders when calculating water needs, assessing hose capabilities, and strategizing fireground operations. This knowledge contributes to effective firefighting tactics, ensuring that adequate water supply is available to combat various types of fires.
