Example: In this example, you need to recall your pressure equation from the pressure lab. Specifically: P = p(g)(depth) You also need to recall that in general P = F/A and therefore, Force = P(A) %3D %3D In this diagram, suppose the green box is Force due fluid pressure pushing on the top of the box 30 сm immersed in fresh water and has all dimension at 40 cm. Suppose the block is 30 cm below the surface of the water. 40 cm Question to answer: What is the pressure at the top and bottom of the box (30 cm and 70 cm below the surface)? P, = Your answer N/m2 Тoр Force due to Gravity Your answer N/m2 Force due fluid pressure Bottom
