I understand that gas flow through a circular tube or pipe will have some understandable effects... for example the pressure drops, and the maximum flow diminishes. I also know that turbulence and the tubing surface has an effect...
Without getting too specific, I just want to understand generally what happens with gas flowing from a larger diameter tube to a lower diameter tube... and not having to factor in turbulence and such... just assuming a smooth flow.
Actually, I'd like to understand flow the other way too... from a small diameter to a larger one. I suppose flow will still go down... but does pressure recover?
What is the numeric relation of things like pressure and flow to changes in diameter?
My intuition suggests that any change to a smaller diameter might be thought of as an orifice of sorts, and that nothing downstream can tell what's happening in the upstream pipe provided that the pressure is the same.
I'd love to see an interactive simulator... it would help me visualize.
Thanks
