Enter the pipe diameter and length into the calculator to determine the gallons per foot of pipe.

## Pipe Volume Calculation Formula

The following formula is used to calculate the volume of water in a pipe per foot.

Gallons per Foot = (Ï€ * (Diameter / 2)^2 * 12) / 231

Variables:

- Gallons per Foot is the volume of water per foot of pipe (gallons)
- Diameter is the diameter of the pipe (inches)
- Ï€ (Pi) is approximately 3.14159
- 231 is the number of cubic inches in a gallon

To calculate the gallons per foot, multiply the volume of the pipe in cubic inches per foot by the number of cubic inches in a gallon.

## What is Pipe Volume Calculation?

Pipe volume calculation refers to the process of determining the volume of liquid a pipe can hold per unit length. This involves understanding the pipe’s diameter and applying geometric formulas to calculate the volume. Accurate pipe volume calculation is crucial in various fields, such as plumbing, irrigation, and fluid dynamics, to ensure efficient system design and resource management.

## How to Calculate Gallons per Foot of Pipe?

The following steps outline how to calculate the gallons per foot of pipe using the given formula.

- First, determine the diameter of the pipe.
- Next, calculate the radius by dividing the diameter by 2.
- Use the formula: Gallons per Foot = (Ï€ * (Diameter / 2)^2 * 12) / 231.
- Finally, calculate the gallons per foot by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
