1. What is the Hollow Square Tube Weight Formula?

The Hollow Square Tube Weight Formula calculates the weight of a square tube based on its outer side length, wall thickness, length, and material density. This is essential for engineering, construction, and manufacturing applications.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Side \) — Outer side length of the square tube (m)
• \( T \) — Wall thickness (m)
• \( Length \) — Length of the tube (m)
• \( Density \) — Material density (kg/m³)

Explanation: The formula calculates the cross-sectional area of the tube walls and multiplies by length and density to get total weight.

3. Importance of Weight Calculation

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

4. Using the Calculator

Tips: Enter all dimensions in meters. Default density is for steel (7850 kg/m³). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: All dimensions should be in meters (m) and density in kg/m³ for the result in kilograms (kg).

Q2: What's the typical density for steel?
A: Carbon steel typically has a density of 7850 kg/m³, which is the default value.

Q3: Can I use this for rectangular tubes?
A: No, this formula is specifically for square tubes. A different formula is needed for rectangular tubes.

Q4: How accurate is this calculation?
A: It's theoretically accurate for perfect square tubes with uniform wall thickness and density.

Q5: What if my tube has rounded corners?
A: This formula assumes sharp corners. For rounded corners, the weight will be slightly less.
