How Many Gallons Per Minute Garden Hose

(Last Updated On: June 20, 2022)

A standard garden hose flows at about 9 to 10 gallons per minute. However, the exact amount of water flow will depend on the hose diameter, length, and the water pressure. To calculate the exact amount of water flow, you can use this formula: GPM = (60 x PSI) / C.D.A.

If you’ve ever wondered how much water flows out of a garden hose per minute, wonder no more! The average garden hose delivers about 9 gallons of water per minute. So, if you have a 1/2″ hose, that’s about 27 gallons per hour, and a 5/8″ hose delivers about 34 gallons per hour.

Of course, the actual amount of water flowing out of your hose will depend on the water pressure.

Garden hose flow rate calculator

If you’re like most gardeners, you’ve had to deal with a hose that just doesn’t seem to deliver enough water to meet your needs. Whether you’re watering the garden or washing the car, you need to know the garden hose flow rate to make sure you’re getting the job done quickly and efficiently. Luckily, there’s a easy way to calculate the garden hose flow rate that you need.

All you need is a few simple tools and a little bit of time. First, you’ll need to find a garden hose that is the right size for your needs. If you’re not sure, you can always consult a gardening expert or the manufacturer of the hose.

Once you have the hose, attach it to a water source and turn on the water.

Next, use a measuring cup or container to catch the water as it comes out of the hose. Start the timer and let the water flow for 30 seconds.

Hose flow rate chart

When it comes to choosing the right hose for your needs, it is important to consider the flow rate. This is the measure of how much water can pass through the hose in a certain amount of time. The higher the flow rate, the more water can be moved in a shorter period of time.

There are a few factors that can affect the flow rate of a hose, such as the diameter of the hose and the length of the hose. The type of material the hose is made from can also affect the flow rate. For example, a hose made from a more flexible material will have a higher flow rate than a hose made from a less flexible material.

When choosing a hose, it is important to consider the needs of the application. If a high flow rate is needed, then a hose with a larger diameter and/or a more flexible material will be needed.

1″ hose flow rate

In order to determine the flow rate of a 1” hose, you must first know the diameter of the hose. The diameter of a 1” hose is 1.067”. With this information, you can use the following equation:

Flow Rate (GPM) = (0.408) x (Diameter^2) x (Length) Where: GPM = Gallons per minute

Diameter = Diameter of the hose (in inches) Length = Length of the hose (in feet) For example, let’s say you have a 100’ long 1” hose.

The flow rate would be:

Flow Rate (GPM) = (0.408) x (1.067^2) x (100) Flow Rate (GPM) = 471.6

What is the psi of a garden hose nozzle

When you turn on a garden hose, water flows out of the nozzle at high pressure. But what is this pressure, and how is it measured? The pressure of the water flowing out of the nozzle is called the psi, or pounds per square inch.

This is a measure of how much force the water is exerting on a given area. So, for example, if the nozzle has a psi of 40, that means that it’s exerting 40 pounds of force for every square inch of area. This pressure is created by the water flowing through the hose.

The narrower the hose, the higher the pressure. So, a garden hose nozzle with a small opening will have a higher psi than one with a large opening. The psi of a garden hose nozzle can range from about 20 to 80.

The higher the psi, the more powerful the stream of water.

how many gallons per minute garden hose


How many gallons per minute is a 3/4 garden hose?

A 3/4 garden hose has a flow rate of about 10 gallons per minute. This flow rate is determined by the diameter of the hose and the water pressure.

How many GPH do I need for a garden hose?

If you have a garden, you need a garden hose. But how do you know how much water flow (GPH) your garden hose needs? The first thing to consider is the size of your garden.

A small garden will need less water flow than a large garden. Use the chart below to determine how much water flow you need based on the size of your garden:

-Small garden (up to 400 square feet): 1-2 GPH

-Medium garden (400-1,000 square feet): 2-3 GPH -Large garden (1,000-3,000 square feet): 3-5 GPH Keep in mind that these are just general guidelines.

If you have a particularly dry climate or if you water your garden more than once a day, you may need more water flow. Now that you know how much water flow you need, the next step is to choose a garden hose that can provide that amount.

How long does it take to fill a 5 gallon bucket with a hose?

Assuming you are using a standard garden hose with a 5/8″ diameter, it will take just over 17 minutes to fill a 5 gallon bucket. This is based on the assumption that the water pressure is 60 PSI and the hose is completely unobstructed.

How many gallons per minute does a hose bib use?

A hose bib typically uses between 3 and 5 gallons of water per minute. This can be higher or lower depending on the size of the hose bib and the water pressure.


If you have a standard garden hose, you can expect it to deliver about 5 gallons of water per minute. But if you have a bigger hose, or one that’s been specifically designed for high-flow applications, it could deliver up to 10 or even 15 gallons per minute.
