This law states that for a static water, the variation of the pressure along the vertical downwards direction is equal to the specific weight of the liquid.
So if 'd' is the specific weight of the liquid, and h is the depth measured from the top surface of the liquid,
then pressure at a point at depth 'd' can be calculated as below
p = d.h (where 'd' is the water density, and 'h' is the depth)
This shows that static pressure at the top surface,
h = 0 , p = 0
and it is maximum when h =H (H is the total depth of the water)
p = d.H
So, this shows the linear variation of the static pressure from top surface to the bottom face.
This can be shown diagrammatically as shown in figure above.
