Prerequisites: Differential Equations (MA3520 or MA3521) and Chemical Engineering Fundamentals II CM2120 and Physics II PH2100. This course will make intensive use of all of your math background (units, algebra, calculus, differential equations, vectors, partial derivatives), your physics background (Newton's laws, forces, torques, angular rotation), and your chemical engineering background (mass and energy balances, macroscopic energy balances, heat exchangers, friction in flow, pumps).
Class hours: MW 3-4:30pm, Fisher 139

TA: Maria Tafur, email: email@example.com, 405 Chem Sci; office hours Tuesdays 4:30-6:30, Fridays by appointment.
Master the principles governing the transport of momentum (fluid flow) and energy (heat transfer) in chemical engineering systems. Master the application of momentum and energy balances to simple systems, master the application of the general differential balance equations to steady problems, and become familiar with the solutions of unsteady-state problems. Introduction to dimensional analysis and empirical methods. Become familiar with techniques to apply these subjects to areas such as pump analysis, sedimentation, fluid meters, heat-exchanger design, or evaporator design.

The reading assignments are listed on the web: www.chem.mtu.edu/%7Efmorriso/cm310/Homework_assignments.html It is expected that this material will be read prior to class time.
There will be four 1.5 hour (90 minute) exams plus a two-hour final exam. The exams will be closed book, closed notes with one 8.5 by 11 sheet, both sides, allowed for formulas. An exam may include any topic covered in the course up to the section indicated in the syllabus for that exam. Make-up exams will not be given except under extraordinary circumstances. Check your final exam schedule early and report any conflicts as soon as possible. Check the syllabus for any conflicts with the scheduled exams and inform the instructor the first week of the term.
The Department has the software Comsol Multiphysics 4.2 (www.comsol.com/), which is a state-of-the art program for solving differential equations. It is designed to calculate solutions to the equations of motion and energy that we study in CM3110 and CM3120. We shall introduce a computer project midway through the term.
First exam: 15%; Second exam: 20%; Third exam: 20%; Fourth exam 20%; Final exam: 25%; Computer Project (Comsol): 5% Scale: 90-105 %A; 86-89 AB; 80-85 B; 76-79 BC; 70-75 C; 66-69 CD; 60-65 D; Less than 60% F
Homeworks will be assigned regularly (see syllabus). The homeworks are designed to focus your attention on the types of calculations that will improve your comprehension of fluid mechanics and heat transfer. Answers to homeworks will be provided; solutions to homeworks will not be provided. You may work on homeworks with your classmates. You may ask for homework help from the TA or from the instructor or from anyone else.
You are encouraged to work together in study groups to trade ideas on how to solve problems and to help to teach each other the subject.
Cheating of any form will not be tolerated. Any student found to be cheating would be reported to the Dean of Students. The punishment for plagiarism ranges from an F in the course to expulsion.
CM3110 only covers the most basic aspects of fluid mechanics and heat transfer. If you are at all interested in pursuing graduate school upon graduating from Michigan Tech, I encourage you to pursue additional readings on fluid mechanics and heat transport while taking this course. Two excellent texts are Denn’s book on Process Fluid Mechanics and Bird, Steward and Lightfoot (BSL), Transport Phenomena:
M. M. Denn, Process Fluid Mechanics (Prentice-Hall, Inc.: Englewood Cliffs, NJ, 1980).
R. B. Bird, W. E. Stewart, and E. N. Lightfoot, Transport Phenomena, 2nd edition (John Wiley and Sons: New York, 2001).
R. B. Bird, W. E. Stewart, and E. N. Lightfoot, Transport Phenomena (John Wiley and Sons: New York, 1960).<>
<>I very much like the text by Frank White, although it is intended for mechanical engineers: F. M. White, Fluid Mechanics, 3rd Edition (McGraw Hill, New York, 1994).
I would also encourage you to take the graduate transport course CM5300, if possible. If you are interested in learning more about non-Newtonian fluids, consider taking CM4650 Polymer Rheology (www.chem.mtu.edu/~fmorriso/cm4650/cm4650.html); which I teach in the spring (note: CM4650 will not run in Spring 2013 due to my sabbatical). CM4650 also gives additional background on Newtonian fluid mechanics.
