take the outside diameter and subtract the thickness twice.
Outer radius minus inner radius Subtract the inside diameter from the outside diameter, then divide the difference by 2.
That would depend on the wall thickness of the pipe. 54 inches is the outside diameter so subtract the pipe wall thickness (x2) adn you have the inside diameter.
For example a tube (hollow cylinder)with wall thickness 't' the outside diameter is: 1.00+2t So if the walls are 1.0mm thick the outside diameter is 1.20cm If there is no wall thickness the inside and outside diameter are the same. This seems a little too simple a question to ask here so I suspect the person asking the question has omitted some details or that they want an answer to a different question.
Then the wall thickness is 1 inch
The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.
-- Subtract the inside diameter from the outside diameter. -- Take half of the result. (since the outside diameter counts both walls of the pipe, and you want only one wall) Now you have the wall thickness. Common example. 1/2" OD, 3/8 " plastic tubing 1/2-3/8=1/8 and now divide by 2 and the wall thickness is 1/16"
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
Calipers are used to measure the dimension of anarticle. In measuring a section of pipe you would use an inside caliper to give the internal diameter, and an outside caliper to give the external diameter. The difference being the thickness of the pipe wall.
Any measurement smaller than 35mm. That measurement would depend on the thickness of the material making the tube
