Interactive Self-Study Module: Material Balances
This module uses screencasts and interactive simulation(s) to explain steady-state material balances around various process units. It then provides example problems and a step-by-step quiz simulation to allow the user to test themselves. Your retention of material in this module will increase if you write down reasons for your answers to ConcepTests, questions in screencasts, and questions to answer before using interactive simulation(s), and you try to solve the example problems before watching the screencast solutions. We suggest using the learning resources in the following order:
- Attempt to answer the multiple-choice ConcepTests before watching the screencasts or working with the simulations.
- Watch the screencasts that describe the general material balance equation and answer the questions within the screencasts.
- Review important equations for material balances.
- Use the interactive simulation(s) to further understand how recycle streams can improve overall yields.
- Use the quiz interactive simulation to test your understanding by carrying out material balances.
- Try to solve the example problems before watching the solutions in the screencasts.
- Answer the ConcepTests.
- Look at the list of key points, but only after you try to list the key points yourself.
- Material balances are used to help solve complex problems around various process units.
- This module is intended for a material and energy balance course.
Before studying this module, you should:
- Be familiar with general chemistry.
- Know how to calculate mass fractions and mole fractions.
After studying this module, you should be able to:
- Perform steady-state material balances around various process equipment.
