Hello,(adsbygoogle = window.adsbygoogle || []).push({});

As we know, when you blow over the neck of a bottle, it resonates at a certain frequency.

I want to build a cylinder that will resonate at a certain wind speed:4 mphor about1.78 m/s

I definitely know how to find the resonant frequency of a cylinder. However, I'm not sure what equation would help me solve for finding what "wind speed" over the top would cause it to resonate!

What am I missing here? Is this a more difficult problem than I anticipate?

Thanks!
