1. What is Pipe Gallons Per Foot?

Pipe gallons per foot represents the volume capacity of a pipe per linear foot. It indicates how many gallons of fluid a pipe can hold for each foot of its length, which is crucial for fluid transport and storage calculations.

2. How Does the Calculator Work?

The calculator uses the pipe volume formula:

\[ \text{Gallons per ft} = \pi \times \left(\frac{\text{Diameter}}{24}\right)^2 \times 7.48 \]

Where:

\( \pi \) — Mathematical constant (approximately 3.14159)
\( \text{Diameter} \) — Pipe diameter in inches
24 — Conversion factor (2×12 to convert diameter to radius in feet)
7.48 — Conversion factor from cubic feet to gallons

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

3. Importance of Pipe Volume Calculation

Details: Calculating pipe volume per foot is essential for determining fluid capacity, planning pipeline systems, calculating flow rates, and designing efficient fluid transport systems in various industries.

4. Using the Calculator

Tips: Enter the pipe diameter in inches. The value must be greater than zero. The calculator will automatically compute the gallons per foot capacity.

5. Frequently Asked Questions (FAQ)

Q1: Why is the diameter divided by 24 in the formula?
A: Dividing by 24 converts diameter in inches to radius in feet (diameter/2 for radius, then /12 to convert inches to feet).

Q2: What is the conversion factor 7.48 used for?
A: 7.48 is the conversion factor from cubic feet to US gallons (1 cubic foot = 7.48052 US gallons).

Q3: Does this calculation work for all pipe materials?
A: Yes, the calculation is based on geometry and applies to pipes of any material (steel, PVC, copper, etc.) as long as the internal diameter is used.

Q4: How accurate is this calculation for real-world applications?
A: The calculation provides theoretical maximum capacity. Actual usable volume may be slightly less due to pipe wall thickness and other factors.

Q5: Can this be used for non-circular pipes?
A: No, this formula is specifically for circular pipes. Different formulas are needed for rectangular, oval, or other pipe shapes.
