1. What is Tube Radius?

The tube radius (R) is half of the outer diameter (OD) of a cylindrical tube. It represents the distance from the center of the tube to its outer surface and is a fundamental measurement in pipe and tubing calculations.

2. How Does the Calculator Work?

The calculator uses the simple radius formula:

Where:

• \( R \) — Tube radius (in)
• \( OD \) — Outer diameter (in)

Explanation: The radius is simply half of the outer diameter measurement. This calculation applies to any circular tube or pipe.

3. Importance of Tube Radius Calculation

Details: Accurate radius calculation is essential for determining flow characteristics, structural integrity, material requirements, and fitting compatibility in piping systems and tubular structures.

4. Using the Calculator

Tips: Enter the outer diameter in inches. The value must be greater than zero. The calculator will automatically compute the radius.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between radius and diameter?
A: The diameter is the total distance across the tube through its center, while the radius is half of that distance.

Q2: Can I use this for inner radius calculation?
A: This calculator specifically calculates outer radius. For inner radius, you would need the inner diameter measurement.

Q3: What units should I use?
A: The calculator uses inches, but the formula works with any consistent unit system (mm, cm, etc.).

Q4: Why is radius important in engineering?
A: Radius affects flow rates, pressure drop, structural strength, and heat transfer characteristics in tubular systems.

Q5: Does this work for non-circular tubes?
A: No, this formula only applies to perfectly circular tubes. Non-circular tubes require different calculation methods.
