Two identical open-topped containers contain identical amounts of water, and they are connected by a tube at their bases. Container A is higher than Container B. How much water, if any, will flow from Container A to Container B? How does this change if the height of container A increases or decreases?
I left this out initially, because I didn't want to influence answers. I expected the water to reach an equilibrium and stop flowing from container A to B. When I tried running the experiment, water flowed from container A until it was emptied. Can someone explain why this happened? Did this happen because of poor design, or is it expected?
