1.2.2. Basic Hydrostatic Concepts

Try these first

1. 1.

   What happens to pressure as you go deeper in a fluid?

   Hint

   Consider the weight of the fluid above.

2. 2.

   What does Pascal's Law state?

   Hint

   Think about how pressure feels when you squirt a tube.

3. 3.

   What principle states that pressure in a fluid at rest increases with depth?

   • Bernoulli's Principle
   • Pascal's Law
   • Hydrostatics

   Hint

   Think of a swimming pool!

4. 4.

   True or False: The pressure at the free surface of a fluid is zero.

   • True
   • False

   Hint

   What do we measure pressure against?

5. 5.

   A dam has a vertical face submerged in water. Calculate the hydrostatic force on a section of the dam 10 m wide and 6 m tall.

   Hint

   Start by calculating average pressure across the height.

6. 6.

   You're designing a water tank. What dimensions would maximize stability given a center of buoyancy higher than the center of gravity?

   Hint

   Think about shapes like a pyramid versus a cube.
