7.6. Pascal’s Law

Try these first

1. 1.

   Define Pascal’s Law.

   Hint

   Think about how pressure behaves in connected containers.

2. 2.

   What does hydrostatics study?

   Hint

   Consider fluids that aren't flowing.

3. 3.

   What happens to pressure in a confined fluid when an external force is applied?

   • A: It decreases.
   • B: It is transmitted equally in all directions.
   • C: It increases only at the point of application.

   Hint

   Think about how connected fluids behave when pressure is applied.

4. 4.

   True or False: In a static fluid, pressure increases with depth.

   Hint

   Consider how weight affects pressure in various fluids.

5. 5.

   Design a small hydraulic lift using Pascal's Law. If a force of 200 N is applied to the smaller cylinder with a diameter of 0.1 m, what is the maximum weight it can lift if the larger cylinder has a diameter of 0.5 m?

   Hint

   Think about how the area ratios relate to force in a hydraulic system.

6. 6.

   An open tank has water up to a depth of 5 m. Calculate the total pressure at the bottom of the tank. How would this change if the tank was filled to a height of 10 m instead?

   Hint

   Use the formula for pressure at a given depth to calculate.
