If the radius of the first bend is 16" and the spacing between conduit runs is 3", what is the radius of the second pipe when making a concentric bend?

To determine the radius of the second pipe while making a concentric bend, one must consider how the spacing affects the overall radius of the second conduit. When two pipes are bent concentrically, the radius of each subsequent pipe increases by the distance of the spacing for each additional conduit run.

In this case, the first conduit has a radius of 16 inches. Given that the spacing between the conduit runs is 3 inches, the radius of the second conduit can be calculated by adding the spacing to the radius of the first conduit.

Therefore, the calculation is as follows:

• Radius of the first bend: 16 inches

• Add the spacing: 3 inches (the spacing between runs)

So, the radius of the second pipe will be:

16 inches + 3 inches = 19 inches.

However, to find the radius of additional pipes beyond the second, you would continue to add the spacing. If the question considered concentric bends of more than two conduits, you would add additional spacing for each conduit.

In this context, if it were to proceed adding spacing beyond just the simple calculation, it can contribute to a radius even higher. Therefore, if considering a scenario where additional spacing is taken into account beyond just the immediate next
