  1. Fluid Mechanics-ISpring 2010 Lecture #05

  2. Hydrostatic Forces on Plane Surfaces

  3. Hydrostatic Forces on Plan Surface • Hydrostatic forces on a plane surface depends upon the weight of the fluid. • For a Horizontal Plate with Area Ab & placed at water depth H • Downward Force=

  4. Hydrostatic Force on Inclined Plane Surface

  5. Center of Pressure

  6. Centroidal MOI for different Cross Sections

  7. Example 2.5 • The gate in Fig. E2.5a is 5ft wide is hinged at point B, and rests against a smooth wall at point A. Compute (a) the force on the gate due to seawater pressure (b) the horizontal force P exerted by the wall at point A (c) the reactions at the hinge B.
