Hydrostatic Force on a Curved SurfaceWe encounter many arbitrarily shaped bodies immersed in liquids such as pipes and walls of containers. Forces on these may be calculated in the same manner as in the previous section. But the required integration of involved terms becomes very tedious. A more simplistic approach is to consider the forces resolved in the three coordinate directions separately. It may be noted that each component of force acts upon a projected area of the body. For example, force in x-direction will act normally on the area projected upon the y-z plane.
Consider a curved surface as shown in Fig.2.15, immersed
in a liquid. The resultant force
