Synopsis

Introduce fundamentals and applications of heat and mass transfer. Develop an understanding of the mechanisms and mathematical representation of conduction, convection and radiation heat transfer and convective mass transfer. Gain an appreciation for the analogies between heat and mass transfer using dimensional analysis. Understand and apply concepts of local and overall heat and mass transfer coefficients including boiling heat transfer to simple problems. Gain an understanding of molecular diffusion in gases, solids, and liquids and develop methods to use these concepts in problem solving. Perform experiments to illustrate the concepts of heat and mass transfer.

Assessment

Laboratory: 10%, Assignments and Tests: 20%
Examination (3 hours): 70%
Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
