I cannot understand the concept of fluid pressure.
Consider a liquid molecule at some point inside a liquid vessel. All the other molecules which are in contact with this molecule will exert normal force upon this molecule. So, this liquid molecule experiences zero net force. If there is no force on the liquid molecule, there will be no pressure because
pressure=magnitude of net force on the area/ area of the surface
If the net force is zero, how will a pressure be exerted at all? Then how does the concept of fluid pressure comes into picture?
