I am a contractor. I install water lines. Once installed we have to pressure test them. We pump the lines up to 150 PSI of water. If the PSI drops one of 2 things is wrong, either i have a leak in the line, or there is a small amount of air in the line. Generally if it is air, it stabilizes in a very short time and we get a passing test. I currently have a line that will not hold a test and I can not find the leak. My question is/are:
1. In an enclosed pipeline, supposing no leak, if there was air in the pipeline and i continue to hydrostatically pump until the pressure stops dropping, what happens to the air?
2. Is there a way to calculate how much air is in the line by how much water it takes to pump it up?
3. What is the air speed velocity of a coconut laden swallow (asking for a friend).
