What is the flow rate for 50' of 2.5" hose used by Engine 3?

The flow rate of 50 feet of 2.5-inch hose can be determined using the specifications typically provided in fire rescue manuals. Generally, for a 2.5-inch hose, the flow can vary based on the nozzle used and the operating pressure.

Given standard flow rates, 50 feet of 2.5-inch hose with a nozzle operating at 100 psi typically flows around 133 gallons per minute (gpm). This value is based on calculations that consider both the diameter of the hose and the friction loss over the length of hose.

Choosing 133 gpm as the correct answer aligns with these benchmarks established in fire training and provides a reliable estimation for operational planning and response scenarios. This decision ensures that firefighters have accurate information for managing hose operations and understanding the capabilities of the equipment being used.
