What is the flow rate of a 2½" (65-mm) handline in general?

The flow rate of a 2½" (65-mm) handline is typically around 250 gallons per minute (GPM). This flow rate is based on standard practices and considerations in firefighting, where larger handlines are used to deliver significant amounts of water to combat fire effectively.

A 2½" hose is designed to allow for a higher volume of water compared to smaller hoses, making it suitable for more substantial firefighting operations, especially in conditions where rapid suppression of flames is essential. The 250 GPM rate allows firefighters to manage larger fires while still maintaining a manageable level of flow for control.

Understanding this flow rate is crucial for firefighters when determining the necessary resources, pressure requirements, and tactics in various firefighting scenarios to ensure efficient use of water and equipment.
