7.1.2. Concepts of Hydrostatic

Try these first

1. 1.

   What is hydrostatics?

   Hint

   Think about fluids that are not moving.

2. 2.

   What does Pascal’s law state?

   Hint

   Consider how pressure acts in all directions.

3. 3.

   What does hydrostatics study?

   • Fluids in motion
   • Fluids at rest
   • Fluids in turbulence

   Hint

   Consider what happens when water is still.

4. 4.

   True or False: According to Pascal's law, pressure applied to a confined fluid is transmitted equally in all directions.

   • True
   • False

   Hint

   Think about how pressure acts in a balloon.

5. 5.

   An engineer is designing a water tank 10 meters deep. Calculate the pressure at the bottom of the tank if the density of water is 1000 kg/m³. Use the formula P = ρgh.

   Hint

   Remember to multiply the density by gravity and height.

6. 6.

   Discuss how changes in atmospheric pressure can affect the height of mercury in a barometer.

   Hint

   Consider how the external pressure affects fluid levels.
