At what speed (flow/volume for that matter) does air leave an outlet when you know it holds x bars in the pipe?(adsbygoogle = window.adsbygoogle || []).push({});

(It goes from x to zero (or athmospheric) -- you know the pressure difference)

I assume you can neglect relative roughness, resistance, and so on as the pressure drop is over such a short distance they do not affect it. The only thing that matters is the size of the hole. Am I in the wrong here?

How would I calculate such a thing?

Thanks for any answer :)
