10.3.1. Basic Principles of Hydrostatic Force

Try these first

1. 1.

   Define hydrostatic pressure.

   Hint

   Think about how weight contributes to pressure.

2. 2.

   What is the center of pressure?

   Hint

   Consider the centroid of the area.

3. 3.

   What increases hydrostatic pressure?

   • Depth
   • Width
   • Temperature

   Hint

   Consider why the pressure at the bottom of a pool is higher than at the surface.

4. 4.

   True or False: The center of pressure is always above the centroid.

   • True
   • False

   Hint

   Think about how pressure varies with depth.

5. 5.

   A rectangular submerged surface is 2 m wide and 4 m high. Calculate the hydrostatic force when the water density is 1000 kg/m³.

   Hint

   Use the formula for hydrostatic force and consider the area.

6. 6.

   Analyze a dam with varying surface shapes below the water line. Outline how you would calculate the force acting on it.

   Hint

   Think about how to break the problem into manageable sections, considering different depths.
