Is the water pressure equal in a sealed column at the top and bottom?

AI Thread Summary
In a sealed column of water, pressure is not equal at the top and bottom; the pressure at the top is lower than at the bottom due to the weight of the water. If the pressure at the center of the column is 1 bar, the pressure at the top will be less than 1 bar, while the pressure at the bottom will be greater than 1 bar. A calculation can be used to determine the pressure difference, typically involving hydrostatic principles. Understanding hydrostatics is essential for calculating these pressure variations. The discussion emphasizes the importance of recognizing how pressure changes with depth in a fluid column.

Is the water pressure equal in a sealed column at the top and bottom?

If I created 1 bar of pressure would this also be equal at the top and bottom?

No. The pressure on the top would be lower than the pressure on the bottom. So the pressure is not 1 bar throughout the column. If the pressure at the center of the column is 1 bar, then the pressure at the top is less than 1 bar, and the pressure at the bottom is greater than 1 bar.

Thank you, is there a calculation I can use to work out the difference?

Have you learned about hydrostatics in your course yet?

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
