1. What is Water Volume per Foot of Pipe?

Definition: This calculator estimates the volume of water contained in one foot of pipe based on its inner radius.

Purpose: It helps plumbers, engineers, and irrigation specialists determine water capacity in pipes for system design and maintenance.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ V = \pi \times r^2 \times 1 \]

Where:

Explanation: The formula calculates the cylindrical volume of water in one foot of pipe using the pipe's inner radius.

3. Importance of Water Volume Calculation

Details: Accurate water volume calculations are essential for system capacity planning, pressure calculations, and chemical treatment dosing.

4. Using the Calculator

Tips: Enter the pipe's inner radius in feet. The result shows water volume per linear foot of pipe.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the inner radius of my pipe?
A: Measure the inner diameter and divide by 2, or check manufacturer specifications.

Q2: Can I calculate for multiple feet of pipe?
A: Yes, simply multiply the result by your pipe length in feet.

Q3: Does this account for pipe material thickness?
A: No, you must use the inner radius (not outer radius) for accurate calculations.

Q4: How do I convert to gallons?
A: Multiply the result by 7.48052 (1 ft³ = 7.48052 gallons).

Q5: What about pipes with different shapes?
A: This calculator is for cylindrical pipes only. Other shapes require different formulas.
