For a 22 1/2° angle in the context of conduit bending, the Shrink Constant is a specific value used to account for the change in length of the conduit as it bends. This value is essential for ensuring that the conduit fits properly after it has been bent, as bending can cause the length of the conduit to shrink or change.

The Shrink Constant for a 22 1/2° angle is typically documented and recognized in various electrical and plumbing codes. The correct value, which relates to how much length is lost in the distance traveled by the conduit during the bending process, is found through empirical data or authoritative references. The value reflects practical observations made during bending procedures.

A common and accepted Shrink Constant for a 22 1/2° angle is indeed 0.20. This means that for every foot of conduit that is bent at this angle, the effective length of the conduit may be reduced by 0.20 feet due to the bending process. This knowledge is crucial for professionals working with conduit systems, as it impacts planning, installation, and material calculations. Understanding the Shrink Constant allows for more accurate installations and helps avoid issues that arise from inaccurate measurements or miscalculations.
