What is the GPM and NP for the Elkhart 4000-24 Chief fog nozzle?

The correct information regarding the Elkhart 4000-24 Chief fog nozzle indicates that it achieves a flow rate of 250 gallons per minute (GPM) at a nozzle pressure (NP) of 50 pounds per square inch (psi). Understanding the specifications of this nozzle is crucial for effective firefighting operations, as the flow rate and pressure dictate how much water can be delivered to combat fires efficiently.

In this case, achieving 250 GPM at 50 psi makes this nozzle a versatile tool for different firefighting situations, providing an optimal balance between flow and pressure. This configuration allows firefighters to apply sufficient water without excessively draining the pump or creating dangerous back pressure situations that could impede the operation of the fire apparatus.

Recognizing proper nozzle specifications like these is essential for firefighters to ensure they are using their equipment to its full potential while adhering to safety regulations and operational effectiveness.
