How many gallons per minute garden hose
The water flow rate from a garden hose typically ranges from 9 to 17 GPM (gallons per minute). For example, a standard 5/8-inch garden hose delivers 17 gallons per minute, while a larger 3/4-inch hose can deliver up to 23 gallons per minute. The interior diameter of the hose is the primary factor that affects the flow rate; the smaller the diameter, the fewer gallons per minute can pass through it.
