Outer Radius of a Hollow Tube Calculator

How to Use This Calculator

1. Enter the Outer Diameter of your hollow tube in millimeters. This is the total width of the tube from one outer edge to the opposite outer edge.
2. Enter the Wall Thickness of your hollow tube in millimeters. This is the thickness of the tube walls.
3. Click the Calculate button to compute the outer radius.
4. The result will be displayed in millimeters.

Understanding the Formula

The outer radius is simply half of the outer diameter. The formula used is:

R = D / 2

Where:

• R = Outer Radius
• D = Outer Diameter

Practical Applications

This calculator is useful in various engineering and construction fields where hollow tubes are used, such as:

• Structural support systems
• Fluid transportation systems
• Heat exchangers
• Circular pipe calculations

Example

If you have a hollow tube with an outer diameter of 100 mm and a wall thickness of 10 mm:

The outer radius would be calculated as:

R = 100 mm / 2 = 50 mm
