Garden Hose Gpm

These calculators use these formulas to determine the water flow rate and time to fill a container with a garden hose.

Garden hose gpm. Water flow rate from the end of the hose gpm an arbitrary number derived from the hose size and supply pressure see table. Using a dynamic water pressure of 15 psi a hose this size will deliver about eight to nine gallons per minute gpm in contrast to a 1 2 inch model of the same length which drops to five to six gpm. Take the square root of 55 psi 57 8 psi which is 0 9755 and multiply by 850 to get 829 16 gpm. A standard garden hose is available in hose sizes of 1 2 5 8 and 3 4 inch.

Because 3 4 inch hoses have a wider mouth their output for a 100 foot hose is slightly larger at 18 gpm but the 25. Select a hose length. The average garden hose gpm would be around 12 to 13 but this can vary depending on the type of hose. The standard 5 8 inch garden hose delivers 17 gallons per minute.

Hose size vs gpm improper hose size is a common mistake when a system is designed. The manufacturer s pressure loss data shows that a 3 inch id hose loses 57 8 psi for an 850 gpm flow. Water flow time. Water flow garden hose litres.

The most popular diameter and length of a garden hose is 5 8 inch by 50 feet. An arbitrary number to account for hose size see table. The same diameter hose at 100 feet long has a much smaller output at 11 gpm. Amount of water flowing from the end of the hose in imperial gallons per min.

Gardeners can rely on estimates even without calculating the hose length. Pressure data for the fire hose. Gpi 113255 4 01n31gm nylon turbine water flowmeter with digital lcd display 3 30 gpm 1 inch fnpt inlet outlet 3 4 out of 5 stars 23 195 99 195. The garden hose that you are using right now is probably one of.

Hose diameter and flow rate hose diameter is one of the major factors that affects flow rate in a garden hose. Water flow garden hose. Select hose diameter and available source pressure. Using undersized hoses can result in pump cavitation back pressure excessive heat and component failure.

The length of hose you need depends on the size of your garden. The measure indicates the interior diameter of the hose. Calculate the exact flow rate by correcting the data to actual pressure loss. Larger hoses such as a 3 4 inch hose use up to 23 gallons per minute.

Look up the specific flow vs.
