[Phys-L] siphon



How to explain siphoning of water using the "energy only" approach?
Yes, each kilogram of water, in the final analysis, loses some
potential energy. But why is its potential energy increasing before
decreasing? Borrowing to pay back later? Remember that the concept of
force (or force per unit area) can not be used to explain the process.
