Objectives To (a) develop a basic understanding of the fundamental mechanisms of heat transfer and their underlying physical principles, as well as a recognition of their relative importance in engineering heat transfer systems, (b) develop a good knowledge of the basic physical laws governing the different fundamental heat transfer mechanisms and the concept of a control volume and (c) become competent in the application of the conservation principles of mass, momentum and energy using the control volume concept to develop differential and integral mathematical equations for the rigorous analysis of physical heat transfer processes in engineering.
