Outer Radius of a Hollow Tube Formula
The following equation is used to calculate the Outer Radius of a Hollow Tube.
R = r + t
- Where R is the outer radius
- r is the inner radius
- t is the thickness of the tube wall
To calculate the outer radius of a hollow tube, add together the inner radius and the wall thickness.
What is the Outer Radius of a Hollow Tube?
Definition:
The outer radius of a hollow tub is defined as the distance from the axial center of the tube to the outer surface area.
How to Calculate Outer Radius of a Hollow Tube?
Example Problem:
The following example outlines the steps and information needed to calculate Outer Radius of a Hollow Tube.
First, determine the inner radius. In this example, the inner radius is measured to be 4 inches.
Next, measure the wall thickness. This hollow tube has a wall thickness of .5 inches.
Finally, calculate the outer radius using the formula above:
R = r + t
R = 4+.5
R = 4.5 inches
