I'm having trouble understanding the Pascal's principle. I don't wanna know about the proof or derivation. But just what it means.
The pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid
As far as I know, the pressure in an enclosed liquid is not same throughout. The deeper you go the more the pressure.
So what does the Pascal's principle mean when you apply an external force to that liquid(or fluid)?
Assume that the pressure caused by the applied force is x pa.
Does the Pascal's principle state that after this force is applied the pressure everywhere in the fluid will be x Pa? Or that it will INCREASE by x Pa?
Let's say that, before applying the force, at some point of the liquid the pressure was k Pa. After applying the force, will the pressure at that point(and every other point of the fluid) be x Pa or k+x Pa?

Pascal's principle means that when you apply a pressure to any part of an enclosed liquid, all pressures within that liquid will increase by that amount. Obviously, the deeper you go into the liquid, the higher the pressure becomes, but the pressure increase from an applied pressure is the same everywhere in the liquid.
