Course Notes
Printed notes will be provided which cover the material presented in some, but not all
lectures. Copies of the overheads used in lectures will be available.
Students Repeating the Course
Students who have attempted ENCH 353 in previous years should talk with Dr Jordan if
they wish to have credit carried forward for previous Heat Transfer assignments.
Concerns
Students with concerns about the course should contact any of the lecturers listed above,
the 2nd Pro Director of Studies (Dr Justin Nijdam), or the Head of Department.
General Policies of the Department
Students may obtain the general policies of the University on matters such as the aegrotat
applications, appeals procedures, reconsideration of grades and special provision for
students with disabilities from the University Calendar. The Departmental assessment
details, Departmental Safety Handbook and Electrical Safety Supplement are distributed to
