Pressure in tank pipe -- Bernoulli Equations

[QUOTE="billy_joule, post: 5464877, member: 515386"] What are you trying to find? Pressure at B? Or Pressure at A? You don't need to consider what's going on at point B to do that. Presumably the pipe vents to atmosphere, so point C must be at atmospheric pressure. That is just bernoulli's equation, you were actually very close to reaching that arrangement : . Use gauge pressure as your datum so P[SUB]C[/SUB] = 0, and let your height datum be at point B so h[SUB]B[/SUB] = 0. Plug all those in and collect like terms and you'll reach the solution you quoted, note that the answer is still guage, not absolute pressure. [/QUOTE]
