Transport Phenomena refers to the study of the motion and balance of momentum, heat, and mass in engineering problems. These three modes of transport are studied concurrently for several reasons: they have similar molecular origins, they yield similar governing equations/principles, they often occur simultaneously, and they require similar mathematical/conceptual tools.

In this section we define and introduce several conceptual tools necessary for studying transport, and answer several pertinent engineering questions:

What are my options in visualizing/conceptualizing the movement of momentum, heat, mass?

- Discuss the relationship between Thermodynamics and Transport Processes
- Summarize the critical aspects of continuum mechanics
- Explain the continuum hypothesis and the origin of its breakdown [Ch 1.1, 1.2]
- Define and give examples of (fluid) property fields [Ch 1.3]

- Differentiate between an Eulerian and Lagrangian description
- Explain the difference between an Eulerian and Lagrangian viewpoints [Ch 3.2]
- Identify and differentiate between streaklines, streamlines, and pathlines [Ch 3.3, 3.4]
- Mathematically derive streaklines, streamlines, and pathlines from an Eulerian velocity field
- Define systems and control volumes and identify when each is a useful frame of reference [Ch 3.5]

By what underlying mechanisms does this transport take place? [Ch 3.1]

- Explain and give examples of the three primary modes of heat transfer [Ch 15.1-15.4]
- Describe the primary modes of mass transfer [Ch 24.1-24.3]
- Identify the underlying forces and conceptual hurdles in
momentum transport
- Name and explain the origin of forces acting on fluids in a control volume [Ch 2.1-2.4]
- Define laminar, turbulent, and transition flow regimes [Ch 12.1]
- Distinguish between external and internal flows
- Explain the meaning of fully-developed flow and calculate the entrance region length necessary for a pipe flow

What global understanding of the problem can be acheived through simple reasoning?

- Apply dimensional analysis to generalize problem descriptions
- Perform simple dimensional analysis, using the Buckingham Pi method [Ch 11.1-11.4]
- Calculate the Reynolds Number and use it to predict flow regimes
