Pipe Volume Calculator Gallons

Pipe Volume Formula:

\[ V = \pi \times r^2 \times L \times 264.172 \]

Pipe Volume (gallons):

1. What is a Pipe Volume Calculator Gallons?

Definition: This calculator estimates the volume of liquid a pipe can hold in gallons based on its radius and length.

Purpose: It helps plumbers, engineers, and DIYers determine pipe capacity for fluid transport, irrigation, or storage applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \pi \times r^2 \times L \times 264.172 \]

Where:

\( V \) — Volume (gallons)
\( r \) — Pipe radius (meters)
\( L \) — Pipe length (meters)
264.172 — Conversion factor (gallons per cubic meter)

Explanation: The formula calculates the cylindrical volume in cubic meters then converts to gallons.

3. Importance of Pipe Volume Calculation

Details: Accurate volume calculations ensure proper system design, flow capacity, and material requirements for piping systems.

4. Using the Calculator

Tips: Enter the pipe radius and length in meters. Both values must be > 0. The calculator automatically applies the conversion to gallons.

5. Frequently Asked Questions (FAQ)

Q1: Why is the radius in meters?
A: The formula uses metric units for consistency with the cubic meter to gallon conversion factor.

Q2: Can I use diameter instead of radius?
A: Yes, but you must divide diameter by 2 to get radius before calculation.

Q3: What's the conversion factor 264.172?
A: This converts cubic meters to US gallons (1 m³ = 264.172 gallons).

Q4: Does this account for pipe wall thickness?
A: No, this calculates internal volume. Use internal radius for accurate results.

Q5: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world factors like pipe deformations may affect actual capacity.
