I have a system like this

When the valve is closed, pressure along any point along the thin tube may be found thru pgh. 1. What about when the valve is opened? 2. Does the top of the jar need to be open? 3. If the top is open?

Bernoulli's reveals that fluid speed is 0 at the bend, and that does not make sense? To apply Bernoulli's one would still have to make the assumption the pressure is pg(C-B)+pg(l), where p is density and l is distance down the thin tube...I'm not sure if this is correct? – Max Petrosky Dec 2 '12 at 16:41
