Answer
The pressure at a point inside a liquid at a depth h
= Atmospheric pressure + pressure due to liquid column
= P0 + hρg
where,
P0 = atmospheric pressure acting on the free surface of liquid
h = depth of the point below the free surface
ρ = the density of the fluid
g = acceleration due to gravity.
