Pressure from WeightThe deeper you go, the more fluid you have above your head, the heavier it is, the higher the pressure on you.

Static Fluid
The pressure in the static case depends ONLY on the depth. The shape of the container does not matter.
Pascal’s Law:Pressure is transmitted undiminished to everywhere in the fluid.
