It has been told to me that atmosphere exert a pressure (known as atmospheric pressure) on the surface (I'll take water surface here). And as we go down into water (any fluid, but for instance I'm taking water) the pressure increases. And this increase in the pressure is independent of the shape of the container and only depend upon the depth below the surface of a water open to the atmosphere. The pressure at depth 'h' below the surface of water is greater than atmospheric pressure by an amount [tex]\rho[/tex].g.h Now the confusion begins from here. First Question If I bend the tube in this way: http://www.naugraexport.com/glass/tube-u.jpg will the pressure will be same at every points having the same height or same depth? Explain if I'm going wrong. Second Question [URL]http://www.vias.org/physics/img/utube.png[/URL] In case like shown above where the surface of liquid is not in same level can we still say that the pressure at any point having same elevation from the floor is at same pressure.
