# How Many Psi Per Foot of Water

A common question we get asked is “How many PSI per foot of water?” The answer, unfortunately, isn’t that simple. Depending on the application, the amount of pressure (PSI) necessary to move water through a hose can vary widely.

In general, hoses are designed to operate at pressures between 40 and 200 PSI. But there are several factors that can affect the amount of pressure required, including: The type of hose (e.g., PVC vs. rubber)

The diameter of the hose The length of the hose The temperature of the water

Water is one of the most essential substances on Earth. Not only does it make up a large portion of our planet, but it is also necessary for all lifeforms to survive. While we often take water for granted, it is actually a very powerful substance.

One way to measure the power of water is by its pressure. The pressure of water is measured in psi, or pounds per square inch. One psi is equal to about 0.0068 atmospheres of pressure.

While the atmospheric pressure at sea level is around 14.7 psi, the pressure of water can vary depending on its depth. For example, water pressures increase by about 1 atmosphere for every 10 meters (33 feet) that you go underwater. This means that at a depth of 100 meters (330 feet), the water pressure would be around 17 times greater than atmospheric pressure!

So how much psi does a foot of water column exert? This depends on the width of the column of water. A narrower column will have more pressure than a wider one because there is less area for the same amount of weight to push against.

Assuming a standard width column of one foot, each foot high would produce 0.433psi worth of pressure. So a ten-foot deep pool would produce 4.33psi and a 100-foot deep pool would produce 43psi!

## Feet of Water to Psi Calculator

If you have ever wondered how much pressure is exerted by a column of water, this helpful calculator can tell you. All you need to do is enter the height of the water column in feet, and it will give you the corresponding pressure in psi. This tool is useful for a variety of purposes.

For example, if you are trying to determine the proper size of a pipe for your needs, or if you are troubleshooting a plumbing problem, knowing the psi can help you find the source of the issue. So what exactly is psi? Psi stands for pounds per square inch, and it is a unit of measurement for pressure.

This means that one pound-force is applied to an area of one square inch.

## What is the Pressure at 10 Feet of Water?

Assuming you are using imperial units, the pressure at 10 feet of water is 2.41 psi. This is because the weight of water increases by approximately 0.433 psi per foot of depth. Therefore, at 10 feet of depth, there is a total weight of 4.33 psi acting on the surface area.

However, atmospheric pressure also acts on the surface area and must be taken into account. At sea level, atmospheric pressure is 14.7 psi. This means that the net pressure at 10 feet of depth is 2.41 psi (4.33 – 14.7).

## What is the Water Pressure at 20 Feet?

Assuming you are asking about water pressure in feet of water, at 20 feet the water pressure would be 0.433 pounds per square inch or 2.976 kilopascals. The pressure would be caused by the weight of the column of water above pressing down on the water below it.

## How Many Psi are in a Foot?

There are 12 inches in a foot, and 2.31 feet in a meter. One pound per square inch (psi) is equal to 6894.76 pascals. This means that there are approximately 45,400 pascals of pressure in one square foot.

## How Much Pressure is Every Foot of Water?

One foot of water creates 0.433 psi of pressure. This is due to the weight of the water pushing down on the object it is in contact with. The more water that is present, the more pressure it will create.

## Conclusion

If you’re wondering how many psi per foot of water is, the answer is 0.433. This means that for every foot of water column that you have, the pressure exerted on the bottom is 0.433 pounds per square inch (psi).
