Homework Statement
Hello, I'm having troubles figuring out what seems to be a pretty simple physics question.
Attached is an image of the problem. what I am trying to solve is how a funnel effects the speed of air. The input velocity (v1) is 30 km/h, and I am trying to find the output velocity (v2) at the end of the funnel. The diameter of the funnel on the big end is 2.5 m (d1) and the output diameter is 2.5 cm (d2). The length of the funnel is 3 m, and the stem at the end is 10 cm (0.1 m).
I think the speed of air would speed up because its being compressed, but I am unsure of which formula to use to solve this problem. Please help me out!
