#### Interactive Self-Study Module: Multipipe Systems

##### Overview:

This module uses screencasts to introduce the basics of multipipe flow. The concept of pipes in series and parallel is explained through equations and simple examples. Your retention of material in this module will increase if you write down reasons for your answers to ConcepTests and questions in screencasts, and you try to solve the example problems before watching the screencast solutions. We suggest using the resources in the following order:

- Attempt to answer the multiple choice ConcepTest and solve the example problem before watching the screencasts
- Watch the screencast that provides an introduction to pipe flow.
- Review important equations for multipipe systems.
- Try to solve the example problems before watching the solutions in the example screencasts.
- Answer the ConcepTests.
- Look at the list of key points, but only after you try to list the key points yourself.

##### Motivation:

- Although multipipe systems are generally not covered in detail, it is important to have a basic knowledge of them.
- This module is intended for fluid mechanics courses.

##### Before studying this module, you should:

- Be able to simplify and apply the energy equation.
- Understand the concept of the Reynolds number (Re) and be able to calculate it.
- Understand and be able to calculate head loss.
- Grasp the concept of friction factor and be able to use it.

##### After studying this module, you should be able to:

- Use the energy equations to calculate multipipe systems.
- Calculate flowrates for different multipipe systems.
- Differentiate between various multipipe systems.
