How is the flow of water through a pipe or hose measured?

The flow of water through a pipe or hose is measured in terms of volume, which reflects the amount of water that passes through a given cross-section of the pipe over a specific period. This is typically expressed in units like gallons per minute (GPM) or liters per second (L/s). Understanding flow rate is crucial in various applications, including firefighting, where it helps determine how quickly water can be delivered to a fire scene.

While pressure is important in the context of how water is delivered through a system, it does not directly indicate the amount of water flowing; rather, it speaks to the force behind the water. Weight refers to the mass of the water itself and is not a standard measure for the flow rate. Distance, although related in some contexts (for example, measuring how far the water travels), does not provide a direct measurement of how much water is flowing through the system. Therefore, volume is the appropriate and most relevant measure for this scenario.
