Danger, the system is not open to the environment other than to air through a very fine mesh screen. This is, I think, a real and hard hydrodynamics problem. Watch postings by FredGarvin. I negected to mention to him that am morally certain the answer lies on the fact that you cannot siphon...

I do not know the answer to this problem, but I expect the simplest pipe shape I am interested in that would cause the original behavior at E would not have the cycles. I really like this puzzle and think it would be a great problem for an advanced physics class.

Tank was filled with E open. That is the oddity.

This is a very curious situation. I have a large water tank on the top of a hill. It supplies a gravity fed water system that works fine. There is an under ground pipe with one end A in the bottom of the tank. The other end E is about 80 feet below A, and has a faucet. None of the pipe is...
