The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water.
The water exerts the same pressure on the base of each vessel.
The water exerts the greatest pressure on the base of vessel S.
The water exerts the greatest pressure on the base of vessel P.
The water exerts the same force on the base of each vessel.
How do you Calculate Pressure
Force(N)/Area(m2)
Force(kg)/Area(mi2)
Area(m2)/Force(N)
