  4. An Introduction

  5. Transport Phenomena: • What ……..……………………… ??? • Why …………………………….. ??? • How …………………………….. ???

  7. Problems: • Class 1 • Class 2 • Class 3 • Class 4

  8. Suggestions: • Always read the text with pencil and paper in hand; work through the details of the mathematical developments and supply any missing steps. • Whenever necessary, go back to the mathematics textbooks to brush up on calculus, differential equations, vectors, etc. This is an excellent time to review the mathematics that was learned earlier. • Make it a point to give a physical interpretation of key results; that is, get in the habit of relating the physical ideas to the equations. • Always ask whether the results seem reasonable. If the results do not agree with intuition, it is important to find out which is incorrect. • Make it a habit to check the dimensions of all results. This is one very good way of locating errors in derivations.
