Course Objective This is a first course in heat transfer. Topics covered include (1) fundamental concepts relevant to heat transfer analysis, (2) steady-state and transient conduction, (3) forced and free convection, (4) external and internal flows, (5) heat exchangers and (6) fundamentals of radiation (time permitting). Contact Hours 3 lecture hours per week, 2 tutorial hours per week, 4 credit hours. Prerequisites MATH 3132; ENG 1460. Textbook Bergman, T.L., Lavine A.S., Incropera, F.P., DeWitt D.P., Fundamentals of Heat and Mass Transfer, 7th Ed., John Wiley and Sons, 2011. Course Content Chapter 1: Introduction. Chapter 2: Introduction to conduction. Read section 2.2.1 for interest only. Chapter 3: One-dimensional steady-state conduction (excluding Sections 3.1.5, 3.5, 3.6.4, 3.6.5, 3.7, 3.8,

and 3.9). Read Examples 3.1 and 3.2. Chapter 5: Transient conduction (excluding Sections 5.3, 5.8, 5.9, and 5.10). Chapter 6: Introduction to convection (excluding material related to mass transfer and the concentration

boundary layer such as Sections 6.1.3 and 6.2.2). Sections 6.4 and 6.5 will be covered differently in class. Omit Section 6.7.

Chapter 7: External flow (excluding material related to mass transfer). Omit Sections 7.2.4, 7.2.5, 7.7, and 7.8. Exclude the derivation of Equations (7.19), (7.20) and (7.23) in Section 7.2.1; these equations, however, will be used.

Chapter 8: Internal flow (excluding Sections 8.6, 8.7, 8.8, and 8.9). Chapter 9: Free convection (excluding Sections 9.7, 9.8, 9.9, and 9.10). Sections 9.2 to 9.4 will be covered

differently in class. Chapter 11: Heat exchangers (excluding finned surfaces in Section 11.2 and Equations (11.1b) to (11.4); we

will use Equations (11.1a) and (11.5)). Omit Section 11.6. Chapter 12: Radiation (a brief introduction, time permitting).

Quizzes, Term Test, and Final Examination

The quizzes, the term test, and the final examinations are open textbook. One double-sided 8 ½ by 11 inch aid sheet is allowed during the quizzes, the term test and the final examination; additional sheets or notes are not allowed during any of these examinations. No problem solutions may be written in the text book or on the aid sheet.

A student card (or equivalent photo identification) will be required at the quizzes, the term test, and the final examination.

Electronic devices other than dedicated calculators are not permitted during the quizzes, the term test, and the final examination. A non-dedicated calculator device serving as a calculator (e.g., a mobile phone running a calculator application) is not allowed.

You may write on the left-hand page in the examination booklet (that material will be marked). There will be no make-up quizzes or term test. The weight of the final exam will be adjusted to include

the weight of any valid missed quiz or term test. Solutions to the quizzes and the term test will be posted on JUMP.

Assignments

Assignments will be made up of problems from the Problem List. Details of the assignments and their due dates will be given in class.

You are encouraged to work on your assignments with your peers, but you must write a solution on your own (i.e., do not copy).

No late submissions of assignments will be accepted. A waiver will only be granted based on medical, compassionate, or university-related travel reasons. Contact the instructor prior to the university-related travel.

Solutions to the assignments will be posted on JUMP. Instructor Prof. Scott Ormiston Room E1-484 EITC Telephone: (204) 474-8639 E-mail: engsjo@cc.umanitoba.ca Web Page http://home.cc.umanitoba.ca/~engsjo/teaching/MECH-3460/ Lectures

Room E2-125 EITC: Tuesday and Thursday 10:00 to 11:15 Electronic devices or systems such as MP3 players, PDAs, iPods, iPads, cell phones, notebook

computers, and other wireless communication or data storage devices are not allowed in the lecture room without prior permission from the course instructor.

Tutorial

Room E2-130 EITC: Wednesday 11:30 to 13:20 The tutorial time will be used for a combination of (1) extra lecture time, (2) working on assignments,

and (3) writing term tests.

Office Hours Mondays: 14:30 to 15:20 and Tuesdays: 13:30 to 14:20, or by appointment. Students are encouraged to make use of the instructor’s office hours (or other arranged meeting times) to discuss any issues related to the course.

Teaching Assistants A teaching assistant (TA) will be present during the tutorial sessions. The TA (or TAs) assigned to the course will be available for consultation throughout the term and may be contacted by email to ask questions or to arrange a meeting. Detailed contact information for the TA (or TAs) will be provided. Important Points to Remember

Attendance at lectures and tutorials is essential for successful completion of this course. There is a lot of interesting material in this course. It would be unwise to fall behind; it is generally too much material to learn in a very short period of time before a quiz, test, or final examination.

The lectures will cover the important and essential features of the material, but time will not allow covering all the details. It will be necessary for you to read the related sections in the text book; the text book is well-written and contains many examples. Also review your lecture notes regularly.

It is crucial that you do problems to understand the details of the analyses. Work through problems from the Problem List and examples from the lectures and the text book without referring to the solution. Do not leave solving problems to the last minute.

In order to help you prepare for the term tests and the final examination, some previous tests and examinations will be made available for review at an appropriate time on JUMP and also on the U of M libraries’ E-Res system.

It is the responsibility of each student to contact the instructor in a timely manner if he or she is uncertain about his or her standing in the course and about his or her potential for receiving a failing grade.

Academic Integrity Students are expected to conduct themselves in accordance with the highest ethical standards of the Profession of Engineering and evince academic integrity in all their pursuits and activities at the University. As such, in accordance with the General Academic Regulations and Requirements of the University of Manitoba, Section 7.1, students are reminded that plagiarism or any other form of cheating in examinations, assignments, laboratory reports or term tests is subject to serious academic penalty (e.g., suspension or expulsion from the faculty or university). A student found guilty of contributing to cheating in examinations or term assignments is also subject to serious academic penalty.
