1. CE 230-Engineering Fluid Mechanics Lecture # 11 & 12 Hydrostatic forces on curved surfaces

2. What is the magnitude of the force P to keep the triangular gate closed.

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

5. The quarter circle shown is 20 ft long. Determine the vertical reaction at the hinge and P needed to hold it in place P 6 ft.

6. What is the hydrostatic force acting on this gate. W is given

7. What P is needed to keep gate closed.

8. Calculate forces acting on the cylinder of known length
