Garden hose diameter, hose length and available household supply pressure all determine the water flow rate from a hose. Because there are so many factors, it's difficult to say what is an average rate. You can calculate your water rate from your own garden hose, however.
Home centres sell garden hoses in 1/2-inch, 5/8-inch, 3/4-inch and 1-inch diameters, with the most popular being 5/8-inch. As hose diameter increases, the water rate increases.
Manufacturers produce hoses in 25-foot increments, from 25 feet to 100 feet or more. As hose length increases, water pressure decreases.
Pressure is the force that pushes water through pipes. Common household water pressure is about 18.1 Kilogram per square inch.
Use a calculator to determine the exact water flow rate of your garden hose -- see the Resources section for an online version. Enter the hose diameter, length, and house supply pressure into the form. The calculator can also determine the time it'll take to supply a particular amount of water.
