1. What is the Pipe Weight Formula?

The pipe weight formula calculates the weight of cylindrical pipes based on their dimensions and material density. It accounts for the cross-sectional area and length to determine total weight.

2. How Does the Calculator Work?

The calculator uses the pipe weight formula:

\[ Weight = \pi \times \frac{OD^2 - ID^2}{4} \times Length \times Density \]

Where:

\( OD \) — Outer diameter in millimeters
\( ID \) — Inner diameter in millimeters
\( Length \) — Pipe length in meters
\( Density \) — Material density in kg/m³ (default 7850 for steel)

Explanation: The formula calculates the cross-sectional area of the pipe wall, multiplies by length to get volume, then by density to get weight.

3. Importance of Pipe Weight Calculation

Details: Accurate weight calculation is crucial for transportation, structural support requirements, and material cost estimation in construction and engineering projects.

4. Using the Calculator

Tips: Enter dimensions in millimeters, length in meters, and material density in kg/m³. All values must be positive with OD > ID.

5. Frequently Asked Questions (FAQ)

Q1: What's the default density value?
A: The default is 7850 kg/m³ (steel density), but you can change it for other materials.

Q2: How to calculate for solid bars?
A: Set ID = 0 for solid cylindrical bars.

Q3: What units does the result use?
A: The result is in kilograms (kg).

Q4: Can I use this for non-cylindrical pipes?
A: No, this formula is specifically for circular cross-sections.

Q5: Why divide by 1,000,000 in the calculation?
A: This converts mm² to m² for consistent units (mm → m conversion squared).
