  1. CE 230-Engineering Fluid Mechanics Lecture # 9 & 10 Hydrostatic forces on plane surfaces

  2. Consider the force that act on the shown plane surface Distribution of hydrostatic pressure on a plane surface

  3. For the tank with width = 2ma) Determine HF on surface BCb) Determine HF on surface AB water 3 m 4 m

  4. Location of center of pressure • From moment equilibrium we will show that ycp = ŷ +Ī / (ŷ A) or ycp - ŷ = Ī / (ŷ A)
