2 cards from this section. Quick, good the night before a test.
Define hydrostatic pressure.
Think about how weight contributes to pressure.
What is the center of pressure?
Consider the centroid of the area.
What increases hydrostatic pressure?
Consider why the pressure at the bottom of a pool is higher than at the surface.
True or False: The center of pressure is always above the centroid.
Think about how pressure varies with depth.
A rectangular submerged surface is 2 m wide and 4 m high. Calculate the hydrostatic force when the water density is 1000 kg/m³.
Use the formula for hydrostatic force and consider the area.
Analyze a dam with varying surface shapes below the water line. Outline how you would calculate the force acting on it.
Think about how to break the problem into manageable sections, considering different depths.
