Heat and Mass Transfer, 3rd Edition, Y A Cengel, McGrawHill Publishing
TT 8 – 9:15 AM; 252 HR
Course Description: Steady and unsteady conduction, convection, and radiation heat transfer.
Pre-Requisite Skills: Students entering this course are expected to have mastered the following skills:
 ME 215
o Employ the First Law of Thermodynamics (conservation of energy) to perform
calculations to determine heat transfer rates through media with non-equilibrium thermal
conditions.
o Employ the principle of Conservation of Mass to determine unknown flow properties
o Define and use thermodynamic properties and energy quantities in calculations
 MA 238
o Differential equations
Co-Requisite Skills: None required, but it would be useful to understand some concepts from:
 AEM 311
o Fluid mechanics
Attendance
Regular attendance is an important factor in learning this difficult material and in performing well in the
course.

Homework Preparation
Homework in the form of reading assignments and problem assignments will be made for each class period.
Solutions to homework problems will NOT be collected or graded. Instead, there will be a short 5 – 15
minute homework quiz at the beginning of the Thursday classes. The lowest homework quiz grade will be
dropped from the average to account for illnesses and other unavoidable situations. Make-up homework
quizzes will not be given under any circumstance.
60%
Two one-hour mid-term exams
On each of the class periods denoted in the syllabus, a 30% exam will be given over the material covered
previously. Make-up exams will not be scheduled except 1) for a valid reason and 2) only when instructor
has been informed prior to the date of the exam.

Final exam
The final is scheduled for Monday, 11 December 2006, 11:30 – 2:00 PM. Make-up final exams will not
be scheduled.
