What is the difference between a 1" and a 1-3/4" hose?

The key difference between a 1" and a 1-3/4" hose lies in how much water each hose can supply, which is determined by the diameter of the hose. A larger diameter allows for a greater flow rate, meaning the 1-3/4" hose can deliver more water than the 1" hose. This increased flow capacity is crucial in firefighting situations, where the volume and speed of water are critical for suppressing fires effectively.

A 1" hose is typically used for smaller applications, such as supply lines or handlines for minor fire incidents, while the larger 1-3/4" hose is designed for more demanding firefighting scenarios where a substantial volume of water is necessary. Understanding this difference helps firefighters choose the right equipment for specific tasks, ensuring they can respond appropriately to various fire conditions.
