My statistical dynamics and other useful areas of physics was sorely lacking in my undergrad education. Take this for instance, at work I need to calculate the gas flow rate from a tube into a very large chamber. I know the diameter of the tube and pressures of the gas.(adsbygoogle = window.adsbygoogle || []).push({});

Bernoulli's equation seems suited for this

(p + (rV^2)/2) = constant

and so should be equal to each other on either side of the tube connection. However for some reason that didn't get me a useful equation, mostly I think because I don't know what basic assumptions to apply. Note that I only need the rate the air is coming through, which is a large effect, and can ignore details that would actually make this problem hard.

I know the density isn't the same on either side, so can I assume the velocity is the same?

If someone could get me started I would greatly appreciated, I get the feeling htis is going to be awful simple when it is laid out correctly
