Question

the outside diameter of a pipe is 5 and 7/32 inches. the wall of the pipe are 5/32 inches thick. find the inside diameter

Answer 1

The inside diameter of the pipe is calculated by subtracting twice of the wall thickness from the given outside diameter.
In mathematical symbols that would be:
ID = OD - 2T
Substituting the known values,
ID = (5 7/32 inches) - (2)(5/32 inches) = 4.9 inches
Therefore, the answer is 4.9 inches
