This is a Kaplan question that gives a drawing of a funnel leading into a test tube. It asks if a liquid is poured through the funnel, where the speed would be the fastest. I chose the lowest point, which was in the test tube with the reasoning that because of Bernoulli's equation, the extra pressure would translate into it being faster.
The answer key says that it is fastest at the narrowest point in the funnel (above the point I chose) because Av=Av, which makes sense; however I was under the impression that the continuity equation applied to the situation where gravity has no effect (ie. when the system is horizontal).
If anyone can clarify the physics behind pouring something, it would be great.
