What is the expected flow from a 1 1/8" tip on a 2 ½" handline?

The expected flow from a 1 1/8" tip on a 2 ½" handline is typically around 250 GPM (Gallons Per Minute). This figure is derived from flow formulae and standard flow charts used in the fire service, which help to determine the discharge capabilities of nozzles based on their orifice size.

A 1 1/8" nozzle tip is designed for a fluid velocity that allows for the efficient handling of water under pressure, which facilitates effective firefighting efforts by producing a combination of reach and volume. The 250 GPM flow rate is optimal for many firefighting scenarios, enabling a balance between high flow for fire suppression and manageable pressure for the operator.

This flow rate is also consistent with common fire service guidelines, which provide baseline expectations for handline operations. Firefighters can rely on these standard calculations for planning and executing their operations effectively.
