External Diameter of Pipe given Load Per Unit Length for Pipes Calculator

External Diameter Formula:

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

N/m
N/m³

1. What is External Diameter of Pipe given Load Per Unit Length?

Definition: This calculator determines the required external diameter of a pipe based on the load per unit length, pipe coefficient, and specific weight of fill material.

Purpose: It helps engineers and designers determine appropriate pipe dimensions for various loading conditions in construction and civil engineering projects.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: The formula calculates the minimum external diameter needed to withstand the given load conditions, considering the pipe material properties and fill characteristics.

3. Importance of Pipe Diameter Calculation

Details: Proper pipe diameter calculation ensures structural integrity, adequate flow capacity, and compliance with engineering standards.

4. Using the Calculator

Tips: Enter the load per unit length (N/m), pipe coefficient (default 1.2), and specific weight of fill (default 1200 N/m³). All values must be > 0. The ±5% indicates the acceptable tolerance range.

5. Frequently Asked Questions (FAQ)

Q1: What is the pipe coefficient?
A: The pipe coefficient is a dimensionless factor that accounts for the pipe material properties and structural characteristics.

Q2: How is load per unit length determined?
A: It's calculated based on the expected loads from soil, traffic, or other external forces acting on the pipe.

Q3: What affects specific weight of fill?
A: The material type, moisture content, and compaction level all influence the specific weight.

Q4: Why is there a ±5% tolerance?
A: This accounts for variations in material properties and calculation uncertainties in real-world applications.

Q5: Can this be used for pressurized pipes?
A: This formula is primarily for buried pipes under external loads. Pressurized pipes require additional considerations.
