What is the flow rate of a standard 1¾-inch fire hose at 100 psi?

The flow rate for a standard 1¾-inch fire hose at a pressure of 100 psi typically falls within the range of 150 to 200 gallons per minute. This flow rate is a crucial parameter for firefighting as it helps in determining how effectively the hose can deliver water to combat fires.

When considering the operational dynamics of a 1¾-inch fire hose, factors such as the diameter of the hose and the pressure help in establishing the expected flow rate. At 100 psi, the pressure provides sufficient force to propel a substantial volume of water, and the size of the hose allows for a good balance between flow rate and maneuverability. This specification is often used in training and operational scenarios to ensure firefighting personnel can effectively manage water supply during emergencies.

In comparison, other flow rate options do not align with the standard expectations for this kind of hose under the specified pressure. Options that suggest significantly higher flow rates are unrealistic for a 1¾-inch hose, as they typically reflect larger diameters or different configurations that are not applicable in this case. Thus, the range of 150 to 200 gallons per minute accurately captures the expected performance of a 1¾-inch fire hose at 100 psi.
