Grading:

2 Midterm exams	20% each
Final exam	35%
Homework	25%

• Lowest score on midterm or half of final exam will be given half weighting
• Exams will be open book and notes, and will include about 40% short-answer type questions.
• Homework problems will typically be assigned Fridays and due the following Friday at 4:30 P.M. Late homework will marked down at the rate of 10 points (out of 100) per working day late. Since everyone has some valid reason for being late on at least one homework assignment, your lowest homework score (or one missing score) will be eliminated.
• Homeworks will include some computer problems

(Possibly) helpful handy hints:

· Exams will tend to mirror lectures rather than text; take reasonably clear lecture notes and be sure you understand the lectures. Please ask questions inside and outside class!

• Watch units on all numerical problems.
• Be sure you know the assumptions and restrictions of all equations you use - one-dimensional, steady, constant k, etc.
• I will have to miss several lectures due to travel commitments; thank you in advance for your cooperation (not that I’m giving you any choice in the matter…)
• Discussion sessions are scheduled only during weeks that homework is due or weeks that a midterm is given, however, a discussion session will be added any other week upon request from a quorum of students

Accreditation Board for Engineering and Technology (ABET) Course objectives:

To introduce the student to the fundamentals of heat transfer by conduction, convection (forced and buoyant) and radiation.

ABET Course Outcomes: The student will be able to

1. Scrutinize a calculated result for “obvious” mistakes

2. Analyze 1-D steady heat conduction in planar, cylindrical and spherical geometry

3. Use conduction shape factors for the calculation of multi-dimensional conduction heat transfer problems and know when shape factors are or are not applicable

4. Employ a spreadsheet program for the calculation of multi-dimensional conduction heat transfer problems

5. Know what the lumped capacitance method for unsteady conduction is, and when it applies

6. Describe the structure of thermal and momentum boundary layers

7. Know the difference between constant-temperature and constant-heat-flux convection problems

8. Apply empirical formulas for forced or buoyant convection to find heat transfer rates or wall temperatures

9. Perform a preliminary design of a heat exchanger

10. Calculate the radiation heat transfer between two or more gray surfaces whose radiation shape factors are known

11. Estimate which mode of heat transfer (conduction, forced or buoyant convection, radiation) dominates a particular system
