What is the nozzle pressure for smooth bore master streams?

The nozzle pressure for smooth bore master streams is typically set at 80 psi. This pressure is essential for maintaining effective flow and distance when delivering water, as it allows the stream to project adequately while achieving optimal reach and penetration for firefighting operations. A nozzle pressure of 80 psi is a standard in the industry, providing a balanced combination of distance, control, and minimal turbulence in the water stream. This ensures that the fire service personnel can efficiently combat flames and protect exposures in various firefighting scenarios, making it a crucial operating parameter for pump operators.
