1. What is Unit Weight of MS Square Pipe?

Definition: This calculator estimates the weight per unit length of mild steel square pipes based on dimensions and material density.

Purpose: It helps engineers, architects, and construction professionals determine pipe weight for structural calculations and material estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( W \) — Weight per unit length (kg/m)
• \( \rho \) — Material density (kg/m³, 7850 for mild steel)
• \( a \) — Outer side length (meters)
• \( b \) — Inner side length (meters)

Explanation: The formula calculates the cross-sectional area (outer area minus inner area) and multiplies by density to get weight per meter.

3. Importance of Unit Weight Calculation

Details: Accurate weight calculation is crucial for structural design, transportation planning, cost estimation, and load-bearing capacity analysis.

4. Using the Calculator

Tips: Enter material density (default 7850 kg/m³ for mild steel), outer side length, and inner side length. All values must be positive, and outer dimension must be larger than inner.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical density for mild steel?
A: Mild steel typically has a density of 7850 kg/m³, but this can vary slightly based on alloy composition.

Q2: How do I measure pipe dimensions?
A: Measure outer side length across one face, and inner side length (if hollow) similarly. Convert millimeters to meters (divide by 1000).

Q3: What if my pipe is solid (not hollow)?
A: For solid square bars, set inner side length (b) to 0.

Q4: Can I use this for rectangular pipes?
A: No, this calculator is specifically for square pipes. For rectangular pipes, a different formula is needed.

Q5: How accurate is this calculation?
A: It provides theoretical weight. Actual weight may vary slightly due to manufacturing tolerances and material variations.
