7.2.2. Fluid Statics Concepts

Try these first

1. 1.

   What is fluid statics?

   Hint

   Think about fluids that are not in motion.

2. 2.

   State Pascal's Law.

   Hint

   Consider hydraulics in machines.

3. 3.

   What principle states that pressure changes in a confined fluid are transmitted undiminished throughout?

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

   Hint

   It's named after a famous French mathematician and physicist.

4. 4.

   Is hydrostatic pressure greater at the surface than at the bottom of the fluid?

   • True
   • False

   Hint

   Think about what is above the point you're measuring.

5. 5.

   Design a dam that can withstand a hydrostatic pressure of 500,000 Pa at its base. What factors must you consider in your design?

   Hint

   What is the relationship between height, density and pressure?

6. 6.

   Explain how a barometer measures atmospheric pressure and derive the basic formula it is based on.

   Hint

   Consider the height of the mercury column and the density of mercury.
