# How many PSI is a foot of head?

## How many PSI is a foot of head?

The relationship between PSI and feet of head is that 2.31 feet of head = 1 PSI. Translated, that means that a column of water that’s 1-inch square and 2.31 feet tall will weigh 1 pound.

## What is the PSI at 100 feet?

Also when calculating pressure at depth the sea level pressure value e.g. 14.7 is not used in the pressure vs. depth calculations and starts at 0. We (Navy divers) have always used 44.5 psi per 100 ft.

**How do you convert pressure to head?**

Pressure can be converted to head (unit of length) by dividing the value by the product of the specific gravity of the fluid and the pressure gradient of water.

**What is a foot of head?**

Feet of Head means the resistance in a hydraulic system based on the equivalent to the height of a column of water that causes the same resistance (100 feet of head equals 43 pounds per square inch). Also see “Total dynamic head”.

### Is head equivalent to pressure?

In simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.

### How do you calculate head feet?

**What is the pump head calculation?**

The head is usually the maximum height that the pump can lift, and is indicated by H. The most commonly used pump head calculation formula is H = (p2-p1) / ρg + (c2-c1) / 2g + z2-z1.

**How many psi per foot of head?**

psi (relative to atmosphere) foot of head (relative to vacuum) More information from the unit converter How many psi in 1 foot of head? The answer is 0.43341651888775. We assume you are converting between pound/square inch and foot of head. You can view more details on each measurement unit: psi or foot of head

## How do you convert head to Psi?

Convert the head in feet to pressure in psi using this calculator based on specific gravity. Formula: p = 0.433 * h * SG Where, p = Pressure in Psi h = Head in Feet SG = Specific Gravity
