What is the flow range for 1.75 inch attack hose?

The flow range for a 1.75-inch attack hose is typically between 40 to 175 gallons per minute (gpm). This size of hose is commonly used in firefighting for initial attack operations due to its balance of manageability and sufficient flow to combat most residential and small commercial fires. The flow range allows firefighters to adapt to various situations; for instance, lower gpm is useful for smaller fires or when conserving water, while higher gpm can be applied in more intense fire scenarios.

Understanding this standard flow range is crucial for effective firefighting tactics, as it helps firefighters choose the appropriate hose size based on the specific demands of the incident. The other options presented do not align with the standard flow characteristics for 1.75-inch hose, making them less applicable in a firefighting context.
