What change in length occurs in rigid PVC conduit for every 100 feet with a temperature change of 10 degrees Fahrenheit?

The specific change in length of rigid PVC conduit due to temperature variations is a result of its coefficient of linear expansion. For PVC, this coefficient is approximately 3.0 x 10^-5 per degree Fahrenheit.

To calculate the length change, you would apply the formula:

Length change = Original length x Coefficient of expansion x Temperature change.

In this case, if you consider a section of conduit that is 100 feet (or 1,200 inches), and with a temperature increase of 10 degrees Fahrenheit, the calculation would be as follows:

Length change = 1,200 inches x (3.0 x 10^-5) x 10 = 0.36 inches.

Since this calculation relates to overall length increase, the closest option that reflects this increase per 100 feet of conduit due to a 10-degree Fahrenheit change is represented by the answer choice provided.

This final figure is approximate, as the specific value might not be directly listed as a precise choice; however, it's important to recognize that it aligns closely with industry standards and common practice in terms of accounting for thermal expansion in installations involving rigid PVC conduit.
