What is the correct GPM and tip pressure for the Handline nozzle?

The correct answer indicates that a handline nozzle typically operates within a flow range of 50 to 350 gallons per minute (GPM) and at a tip pressure of 100 pounds per square inch (psi). This flow range and pressure are commonly accepted standards for handline operations, ensuring that firefighters have an effective water stream to combat various fire scenarios.

Operating at 100 psi allows for a balance between achieving adequate reach and the ability to manage the nozzle effectively. This pressure also provides the necessary velocity for reaching the seat of the fire while allowing the firefighter to maintain control over the nozzle's operation, which is crucial for safety and efficiency. The range of 50 to 350 GPM covers a variety of firefighting situations, from smaller residential fires to larger commercial structures, accommodating the different water flow needs depending on the type and size of the fire being addressed.

Understanding the flow and pressure relationship is vital for effective firefighting tactics, ensuring that the right amount of water is delivered at the correct pressure for optimal firefighting effectiveness.
