Calculate Gallons per Feet of Pipe

Pipe Volume Formula:

\[ V = \pi \times \left(\frac{d}{2}\right)^2 \times 0.3048 \times 264.172 \]

Volume (gallons per foot):

1. What is Gallons per Foot of Pipe Calculator?

Definition: This calculator estimates the volume of liquid a pipe can hold per linear foot, measured in gallons.

Purpose: It helps engineers, plumbers, and irrigation specialists determine pipe capacity for fluid transport systems.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \pi \times \left(\frac{d}{2}\right)^2 \times 0.3048 \times 264.172 \]

Where:

\( V \) — Volume (gallons per foot)
\( d \) — Pipe diameter (meters)
\( 0.3048 \) — Meters to feet conversion
\( 264.172 \) — Cubic meters to gallons conversion

Explanation: Calculates the cross-sectional area of the pipe, converts to volume per foot, then converts to gallons.

3. Importance of Pipe Volume Calculation

Details: Accurate volume calculations are essential for system design, flow rate calculations, and chemical dosing.

4. Using the Calculator

Tips: Enter the pipe diameter in meters. The result shows how many gallons the pipe holds per linear foot.

5. Frequently Asked Questions (FAQ)

Q1: Why is diameter in meters but result per foot?
A: The formula converts meters to feet internally (0.3048 factor) while using metric diameter input.

Q2: Does this work for any pipe material?
A: Yes, the calculation is independent of pipe material as it only considers internal diameter.

Q3: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real pipes may vary slightly due to manufacturing tolerances.

Q4: Can I use inches for diameter input?
A: Convert inches to meters first (1 inch = 0.0254 meters) or modify the formula.

Q5: Does this account for pipe wall thickness?
A: No, use internal diameter for accurate results. Subtract twice the wall thickness from outer diameter.
