Answer to Question #18015 in Mechanics | Relativity for Basel

Question #18015
subject .. pressure

If wwe have 2 different cross sectioned tubes filled with with 2 similar liquids with the same density and height , when is the pressure different?
Expert's answer
Pressure = density * gravity *height, so the pressure is same in both tubes, despite them having different cross sections.

The cross section would impact the mass and weight of the liquids, but not the pressure.

Pressure difference, if any, could be caused by external (e.g. atmospheric) pressure, or mechanical motion (e.g. rotation, etc.).
