think of a funnel, the top is bigger than the bottom. you can pour something in the top slow and it comes out faster at the bottom. if you move, say, 500 cubic inches of water through a 1 inch opening in 1 minute it doesn't have to flow as fast, but if you push it through a 1/2 inch hole, it has to flow a lot faster in order to get the same amount of fluid out in the same amount of time. Get it?
