1. What is the PVC Pipe Volume Formula?

The PVC pipe volume formula calculates the internal capacity of a pipe in gallons based on its inner diameter and length. This is useful for determining fluid capacity in plumbing, irrigation, and other piping systems.

2. How Does the Calculator Work?

The calculator uses the PVC pipe volume formula:

\[ V = \pi \times (ID/24)^2 \times L \times 7.481 \]

Where:

\( V \) — Volume in gallons
\( ID \) — Inner diameter in inches
\( L \) — Length in feet
7.481 — Conversion factor (cubic feet to gallons)

Explanation: The formula calculates the cylindrical volume in cubic inches, converts to cubic feet, then to gallons.

3. Importance of Pipe Volume Calculation

Details: Knowing pipe volume is essential for system design, chemical dosing, flushing procedures, and capacity planning in plumbing and industrial applications.

4. Using the Calculator

Tips: Enter inner diameter in inches and length in feet. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide ID by 24 in the formula?
A: This converts diameter in inches to radius in feet (12 inches per foot, divided by 2 for radius).

Q2: Does this work for pipes of any material?
A: Yes, the formula works for any cylindrical pipe, though it's most commonly used for PVC in practice.

Q3: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real pipes may have slight manufacturing variations.

Q4: Can I calculate volume in liters instead?
A: Yes, multiply the gallon result by 3.78541 to convert to liters.

Q5: What about pipes with different wall thicknesses?
A: This calculation uses inner diameter only. Wall thickness affects outer diameter but not volume.
