1.4. Definitions and applications in fluid statics

Try these first

1. 1.

   What happens to fluid pressure as you dive deeper underwater?

   Hint

   Think about the weight of the water above you.

2. 2.

   State Pascal's Law in your own words.

   Hint

   Consider how a hydraulic lift works.

3. 3.

   What law states that pressure applied to a confined fluid is transmitted equally in all directions?

   • Archimedes' Principle
   • Pascal's Law
   • Bernoulli's Principle

   Hint

   Recall the principle related to hydraulic systems.

4. 4.

   True or False: Pressure increases with depth in a fluid.

   • True
   • False

   Hint

   Think about why divers need pressure suits.

5. 5.

   A dam has a water depth of 20 meters. If the density of water is 1000 kg/m³, calculate the pressure exerted at the base of the dam.

   Hint

   Use the formula for pressure based on depth.

6. 6.

   If two objects of different densities are submerged at the same depth, which will experience a greater buoyant force, and why?

   Hint

   Remember what Archimedes’ principle states about buoyant force.
