This course provides theory and application of steady and transient heat conduction in solids. The topics include forced
convection, mathematical development of thermal boundary layer, natural convection and heat transfer correlation
equations. The thermal radiation equations with application to heat exchange between black and gray bodies are
developed. Heat exchangers are also covered in this course.
Prerequisites: EG201 (Fluid Mechanics), EG209 (Thermodynamics), and MA205 (Differential Equations)
COURSE OBJECTIVE
The goals of this course are to give the student an understanding of the three basic mechanisms of heat transfer. This
includes conduction, convection and radiation heat transfer, heat exchanger design, and how to solve typical heat transfer
problems in both steady and unsteady conditions.
COURSE OUTCOMES
The student will be able to
1. Understand and make calculations in steady and unsteady heat conduction (HW #1-5, test #1, final exam);
2. calculate typical external and internal forced convection and natural convection problems using correlation
equations (HW #6-9, test #2, final exam);
3. calculate the performance of simple heat exchanger designs (HW #10-11, test #3, final exam);
4. understand radiation heat transfer between typical black body and gray body configurations (HW #12, final
exam);
5. design and perform basic experiments in heat transfer and analyze the results (Lab);
6. perform basic thermal design based on hand calculations and commercial software packages (Project #1);
7. have a knowledge of current issue of heat transfer related topics (Project #2).

CLASS ATTENDANCE AND PARTICIPATION
Class attendance is required. In this course you will be expected to act in a professional manner. Among other things this
includes showing up on time prepared for the task at hand. It should include not just being on time for class, but also for
the additional outside meetings you will have with your group. Active participations in class activities are expected.
Classroom activities such as chatting, use of computer, ipod, cell phone and other electronics are not allowed.
Note that if you are more than five minutes late for class you will be marked absent. A reasonable absence is allowed
only if informed in advance and promised to make up except for extreme emergency. However, make-ups for tests and
laboratories will be NOT allowed.
HOMEWORK POLICY
Homework is assigned every week. Talk to me in advance if you have reasonable reasons of not being able to turn in
homework in time. To be fair to all students, late homework or other assignments are given a 20% reduction in points for
the first time, 40% for the second time, and late homework is not accepted for the third times or more. Any homework late
more than 24 hours gets a zero grade.
ACADEMIC HONESTY
While it is assumed that no student/group would submit any material, be it homework, tests, or any other assignment for
grading which is not solely her/his own work, the following policy shall be implemented in cases of academic dishonesty:
First offense, all persons involved will receive no credit for the assignment or test.
Second offense, all persons involved will receive a grade of F for the course.
Please note that I am required to report all offenses to the Provost.
However, the homework or other assignments are encouraged to be done in a group environment with discussions and
change of ideas, as long as understandings are achieved, rather than simply copying.
STUDENT WITH DISABILITIES (ADA Compliance)
If you wish to receive Academic Accommodations at Daniel Webster College in the fall, please contact the Office of
Academic Affairs at academicaffairs@dwc.edu or 577-6615 to arrange a meeting within the first two weeks of the fall
2009 semester. Our meeting is extremely important, as it allows us to prepare your accommodations for the upcoming
semester. Should you not wish to receive accommodations, or fail to arrange a meeting, you will be subject to all
academic standards in your courses.
Please note: In order for a student to be accommodated for a disability under ADA law, the individual seeking disability
accommodations must disclose to the appointed disability coordinator. Disclosure to a staff, faculty or other campus
affiliate does not determine eligibility or grant a student reasonable accommodations.
PEER-TUTORING RESOURCES
Daniel Webster College offers various tutoring resources for all students to utilize. If you feel you need tutoring in a
course that you are currently enrolled, please contact the Dean of your School of study to make an appointment to review
your needs. Your Dean will work closely with you and our Peer-Tutoring Coordinator to arrange appropriate tutoring as
well as if deemed necessary to develop an academic plan with you that will assist with keeping you on track to achieve
your educational goals. Should you need Writing or Math/Science Support, you will be referred appropriately to the
Writing Center and the Math/Science Support Center for further assistance.
COURSE OUTLINE AND HOMEWORK ASSIGNMENTS
Homework problems from the text will be assigned on a regular basis and subject to change. A limited number of other
assignments not in the text might be given. It is expected that the interested student will endeavor to solve these problems.
Remember that you cannot adequately learn this material without practicing the methods.
