How does that reconcile with the syphon principle? You'd figure that once the water is flowing out of the end, even if the tank was below some of the water's path, the flow would continue until all the water was gone.
- mnw21cam 4y agoSiphons work best once air has been excluded from the path. In fact, they work exactly as the opposite to why this maze isn't draining the whole source tank. In a working siphon, the head of water in the downwards direction is greater than the head of water in the upwards direction, which pulls the water forwards. In this case, because of the air columns in the down direction, there is a greater head of water in the upwards direction than the downwards direction, causing a reverse back-pressure.
- CrazyStat 4y agoYep. It's easy to test for yourself that a siphon will quickly stop working if you let too much air into it. This is also why you can't make very tall siphons, as if the pressure gets too low at the top the water will boil off, create a gas pocket of water vapor, and stop the siphon.
