What is the appliance friction loss that must be included for a Blitzfire monitor when flowing over 350 GPM?

The appliance friction loss for a Blitzfire monitor when flowing over 350 gallons per minute (GPM) is correctly identified as 10 psi. This value is crucial to consider because appliance friction loss accounts for the resistance to flow that occurs within the appliance itself, such as the monitor.

At higher flow rates, such as those exceeding 350 GPM, the internal structure of the monitor contributes to increased turbulence and resistance, thereby resulting in additional pressure loss. This specific value of 10 psi is standard for many high-flow appliances, including the Blitzfire monitor, and is used to ensure that firefighters have sufficient pressure at the nozzle to effectively combat fires.

Understanding this concept is vital for Mobile Pump Operators as it aids in accurately calculating the total pressure needed at the pump. Properly accounting for friction loss helps maintain effective water flow and pressure during firefighting operations, ensuring safety and efficiency.
