What is the pressure range for E2's residual pressure?

The residual pressure range for E2 being 20 to 50 psi is significant in firefighting operations. This pressure range is essential for ensuring that the system operates effectively while providing adequate water supply to fire hoses during operations.

In practice, maintaining a residual pressure of 20 to 50 psi is optimal for providing sufficient flow and pressure at the nozzle, facilitating effective firefighting efforts. Staying within this range helps to minimize the risks of creating insufficient pressure that could hinder water flow or, conversely, excessive pressure that could lead to equipment failures or safety hazards.

Understanding this pressure range is also integral when managing hose lines and nozzles in dynamic environments where varying conditions may affect performance. Properly trained personnel can monitor and adjust the pressure to maintain optimal performance, ensuring that firefighters have the necessary resources to combat fires effectively.
