question about water pressure

[loop888]

thank you for your answer rlortie 

now, re-reading the nightlife's answer, which i did not understand at all before, i have some shade of doubt about my theory and your answer.

I did answer that for you by stating that any pressure applied will only intensify the outward pressure of the volume inside at all points.

maybe the pressure in the bigger areas would also push outwards?

rlortie, i think i understad your brake system example, but im not sure if we can compare that with what im asking, because maybe the brake system are separated pressure systems and in my example water (fluid) is only one and pressure applies in the same way all around.   

now im more  confussed 

any one else???

I still don’t think you understood what I was saying. Let me try again.

If you add a pressure to a air tight container, the pressure added will be evenly distributed to the pressure all the walls already have. The walls will first expand outward where they have the least resistance. The least resistant is the center between two resistances.

yes you can compare it, air like water seeks its own level. It does not matter if it is contained in one container or a multitude of containers, as long as they are interconnected any pressure variance will equalize through out the system.

Take two expandable containers one large and one small, run an air tight  hose between them. push them under water, the small container will start expanding as the area of the large container pushing inward creates more pressure due to the larger area of compression. 

The water increases in PSI the farther you sink it and the air increases in PSI  pushing outward pressure, or psi remains the same in both containers but the smaller one has less area being pressed inward

now that image help me so much to understand it, thanks a lot!!
