For smooth bore, what is the prescribed PSI for the Master Steam nozzle?

The prescribed PSI for the Master Stream nozzle being 80 psi is based on the operational characteristics and performance requirements of smooth bore nozzles. Smooth bore nozzles are designed to deliver a specific flow rate and pressure to achieve optimal reach and effectiveness during firefighting operations.

At 80 psi, the smooth bore nozzle provides a balanced combination of a wide reach and adequate flow rate necessary for suppressing fires effectively. This pressure also helps maintain the integrity of the water stream, minimizing the impact of turbulence, which is crucial for long-range application.

Firefighting strategies often involve understanding the dynamics of water flow mechanics, and utilizing the correct PSI ensures that the nozzle operates efficiently, providing the firefighter with the necessary control and effectiveness in emergencies.
