What is the typical flow rate of a 1 3/4" attack hose?

The typical flow rate of a 1 3/4" attack hose commonly ranges from 120 to 180 gallons per minute (GPM). This flow rate is essential for firefighting operations, as it provides sufficient water to effectively combat fires, particularly in residential and light commercial settings. The specific diameter of the hose and its design allow for efficient water delivery while maintaining manageable pressure, making it a standard choice for many fire departments.

In practical terms, the 1 3/4" hose is favored for its balance between flow capacity and maneuverability, which is especially important in firefighting scenarios where speed and flexibility are crucial. The chosen flow rate supports effective extinguishment while minimizing the risk of hose collapse or excessive back pressure, ensuring that firefighters can operate safely and efficiently at the fire scene.
