Gallons per ft 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 ft 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)
\( \pi \) — Mathematical constant Pi (~3.1416)
0.3048 — Conversion factor (meters per foot)
264.172 — Conversion factor (gallons per cubic meter)

Explanation: The formula calculates the cross-sectional area of the pipe, converts it to volume per foot, then converts cubic meters to gallons.

3. Importance of Pipe Volume Calculation

Details: Accurate pipe volume calculations are essential for system design, flow rate calculations, and capacity planning in plumbing and irrigation systems.

4. Using the Calculator

Tips: Enter the pipe diameter in meters. The diameter must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is diameter in meters but result per foot?
A: The formula includes conversion factors to maintain SI unit inputs while providing US customary unit outputs.

Q2: Can I use this for pipes of any material?
A: Yes, the calculation is independent of pipe material as it only considers internal diameter.

Q3: How accurate is this calculation?
A: It provides theoretical maximum capacity. Actual capacity may vary slightly due to manufacturing tolerances.

Q4: What if my pipe diameter is in inches?
A: First convert inches to meters (1 inch = 0.0254 meters) before using the calculator.

Q5: Does this account for pipe wall thickness?
A: No, you should use the internal diameter of the pipe for accurate results.
