Interactive Self-Study Module: Properties of Fluids

This module uses screencasts to describe what a fluid is and some of the important properties of fluids. Example problems allow the user to test themselves. We suggest using the learning resources in the following order:

  1. Attempt to answer the multiple-choice ConcepTest and example problem before watching the screencasts or working with the simulations.
  2. Watch the three screencasts that describe fluid properties and answer the question within the first screencast.
  3. Use the interactive simulation to further understand capillary action.
  4. Try to solve the two example problems before watching the solutions in the screencasts.
  5. Answer the ConcepTests.

Understanding properties of fluids is crucial for concepts later described in fluid dynamics. 

This module is intended for fluid mechanics courses.

Before studying this module, you should:

  • Be able to apply the ideal gas law.
  • Be able to calculate vapor pressure.

After studying this module, you should be able to:
  • Determine what can be considered a fluid.
  • Identify what a shear stress is.
  • Use and describe density, specific gravity, specific weight, the bulk modulus, vapor pressure, and surface tension in engineering applications.
  • Calculate the height of capillary rise.
