The reason I ask is, since the diameter is hollow, there is no mass for expansion, basically no inch/degree F. The circumference would grow like a flat plate, but the Delta in circumference would add to the original circumference. The new diameter would be (Delta + Circumference)/PI. This...
I am on the road and looking for some help.
What is the correct way to determine the thermal expansion (in) for the diameter of say a large diameter (120" OD x .75" thick steel cylinder? Is it based on the increase in the circumference then calculating the nominal diameter similar to rolling a...
