Understanding static pressure energy in Bernoulli’s equation
Thread Content
I would like to ask why, at the 6-6’ section in the problem, p (static pressure energy) = 0 (gauge pressure)?
Is there a problem? It is in contact with the atmosphere; the pressure at this location is therefore atmospheric pressure, and the pressure measured using a gauge is 0
This value represents atmospheric pressure; the pressure measured using a pressure gauge is 0
Connected to the atmosphere! Suddenly it makes sense: lol
On both sides of the equal sign, gauge pressure is used; since it is in communication with the atmosphere, the gauge pressure is zero. Absolute pressure can also be used, as long as it is consistent on both sides of the equal sign :)
