Liquid pressure is due to the weight of liquid acting on the surface of any objects in the liquid.
P = Pressureρ = density of liquid
g = Gravitational Field Strength
Liquid pressure increases with depth. The deeper the object in the liquid, the higher the pressure exert on the object.
Pressure acts in all direction perpendicularly to the surface area of the object.
Pressure in liquid does not depends on
- the size of the container.
- the area of its surface
- the shape of the container 
Pressure in liquid depends only on its vertical distance from the surface of the liquid.
Pressure at A = Pressure at B
