What is the flow rate for a 1.75-inch hose?

The flow rate for a 1.75-inch hose typically ranges between 120 to 180 gallons per minute (gpm). This measurement is significant in firefighting operations as it allows firefighters to understand the volume of water that can be delivered to suppress a fire effectively. A flow rate within this range is often sufficient for handling residential and light commercial fires, making it a standard choice for many firefighting situations.

This range is based on the hydraulic calculations and empirical data available from fire service practices, which indicate that a hose of this diameter can efficiently deliver enough water to achieve effective cooling and extinguishment in most fire scenarios. Understanding the flow rates is essential for firefighters when planning tactics and ensuring that the necessary water supply is available during fire suppression operations.
