I‘m creating notes on thermal expansion, and in my book there is a graph and a table. But they do not represent each other. There will be questions on the mid term, however my teacher is a twit and doesn‘t know which one is right (he‘s a cruddy teacher). I have not been able to find any information online in relation to this information:Thermal expansion of pipe in inches per 100 feet from 70 degrees fahrenheit.Including these materials:Copper, aluminum, cast iron, intermediate alloy steel, carbon steel/carbonmoly steel/low-chrome steel, PVC, and austenitic stainless steel.(mainly copper, cast iron and PVC are the ones I‘m interested in).If you can help me find this somewhere online, you are a miracle worker.
The search term you need is: coefficient of thermal expansion (which will produce thousands of hits). Your text should explain that a coefficient of thermal expansion contains no dimensions. It is merely a ratio with respect to temperature difference. Expansion is a fundamental property found in any table of physical properties. Copper, for example, has a coefficient of 17 × 10^-6/per degree C 100 feet (or meters, or miles, or inches) increases it's length by 17×10^-6/C That is: 100ft × 17× 10^-6 17 × 10^-4 ft per degree C Therefore 100ft copper tube heated 100C becomes 100.17 ft
