7.. Fluid Mechanics

Try these first

1. 1.

   What does Pascal's Law state?

   Hint

   Think about how a syringe works.

2. 2.

   What is hydrostatic pressure?

   Hint

   Consider how pressure changes in a swimming pool when you dive deeper.

3. 3.

   What is the fundamental idea of Pascal's Law?

   • Pressure is constant across all fluid areas.
   • Pressure decreases with depth.
   • Pressure is transmitted equally in all directions.
   • All fluids are incompressible.

   Hint

   Consider how a balloon behaves when squeezed.

4. 4.

   True or False: Hydrostatic pressure decreases as depth increases.

   • True
   • False

   Hint

   Remember the water pressure difference in a swimming pool.

5. 5.

   A water tank has a cylindrical shape with a height of 10m and a diameter of 3m. Calculate the total force on the bottom of the tank due to water pressure.

   Hint

   Remember to calculate the area of the base first.

6. 6.

   Explain how hydraulic lift systems utilize Pascal's law to lift heavy objects.

   Hint

   Consider how force is transferred in confined fluids.
