Try these first

1. 1.

   What happens to pressure as we go deeper into a fluid?

   Hint

   Consider the relationship between depth and pressure.

2. 2.

   Define buoyancy in your own words.

   Hint

   Think about how objects behave in water.

3. 3.

   What is the formula for hydrostatic pressure?

   • P = ρgh
   • P = ρgt
   • P = θρg

   Hint

   Think about which factors affect pressure!

4. 4.

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

   • True
   • False

   Hint

   Consider how pressure acts on submerged surfaces.

5. 5.

   Determine the force acting on a rectangular gate of dimensions 1m x 2m located at a depth of 3m in water. Calculate the force on the gate and the location of the center of pressure.

   Hint

   Start with the hydrostatic pressure formula and area calculations.

6. 6.

   A cylinder submerged in liquid has a height of 1.5m, and the atmospheric pressure is 101325 Pa. Calculate the pressure at the bottom of the cylinder.

   Hint

   Consider both atmospheric pressure and hydrostatic pressure.
