This chapter focuses on the fundamental concepts of fluid statics, specifically surface forces and body forces. It covers the forces exerted on plane and curved surfaces, the determination of buoyant force, and the calculation of resultant forces and center of pressure. The important relationships involving pressure, area, and centroid are established to support the understanding of these concepts.

This chapter focuses on the fundamental concepts of fluid statics, specifically surface forces and body forces. It covers the forces exerted on plane and curved surfaces, the determination of buoyant force, and the calculation of resultant forces and center of pressure. The important relationships involving pressure, area, and centroid are established to support the understanding of these concepts.
The resultant force on a surface is equal to the pressure at the centroid multiplied by the total area.
The center of pressure does not coincide with the centroid due to varying pressure with depth.
The moment of inertia plays a crucial role in determining the location of the center of pressure.
The net force acting on a surface due to fluid pressure, typically calculated as the product of pressure at the centroid and the area.
The point where the total pressure force acts, which differs from the centroid because of variations in pressure with depth.
The upward force exerted by a fluid on a submerged body, related to the weight of the fluid displaced.
The moment created by the pressure forces acting on a submerged surface, used to determine the center of pressure.
