1. What is Pipe Coefficient given Load Per Unit Length?

Definition: This calculator determines the pipe coefficient (C_p) based on the load per unit length, specific weight of fill material, and pipe diameter.

Purpose: It helps engineers and designers evaluate pipe performance under load conditions.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ C_p = \frac{W}{\gamma \times D^2} \]

Where:

\( C_p \) — Pipe coefficient (dimensionless)
\( W \) — Load per unit length (N/m)
\( \gamma \) — Specific weight of fill (N/m³)
\( D \) — External diameter of pipe (m)

Explanation: The load is divided by the product of specific weight and the square of pipe diameter.

3. Importance of Pipe Coefficient Calculation

Details: Proper calculation ensures pipes can withstand external loads and helps in selecting appropriate pipe materials and dimensions.

4. Using the Calculator

Tips: Enter the load per unit length, specific weight of fill, external diameter, and tolerance percentage (default 5%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical pipe coefficient range?
A: Values vary widely but typically range from 0.1 to 10 depending on pipe type and loading conditions.

Q2: Why include a tolerance value?
A: The tolerance accounts for variations in material properties and installation conditions (±5% is common).

Q3: How do I determine the load per unit length?
A: Calculate based on soil weight, surface loads, and other factors acting on the pipe.

Q4: What affects specific weight of fill?
A: Material type, moisture content, and compaction level all influence specific weight.

Q5: When would I need to adjust the tolerance?
A: For critical applications or when using materials with higher variability, you might increase the tolerance.
