I would like to calculate the new diameter and thickness of a steel pipe filled with water.(adsbygoogle = window.adsbygoogle || []).push({});

At 20oC the pipe ID is 0.1016m and thickness is 0.0127m.

Coef vol th exp water 21e-5/oC

coef lin th exp steel 1.2e-6

The pipe can be assumed 1m in length.

I calculated that the water would expand by 1.89e-5m^3 and if there was a solid steel cylinder replacing the water it would expand by 3.25e-6m^3.

So, assuming water is incompressible I think I can not ignore the expansion of the water.

In this case do I take the expansion of the water only to calculate the new ID?

How then do I calculate the new thickness of the pipe?

I'm confised.

Any help appreciated.
