### 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. Calculation of overall heat transfer coefficient and heat transfer area using Log Mean Temperature Difference (LMTD) and Number of Transfer Unit (NTU) method. 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.

### Outcomes

At the conclusion of this unit, students should be able to:

1. Define various modes of heat transfer (conduction, convection and radiation) and mass transfer (diffusive and convective) and the mathematical representations of their rates of transfer.
2. Analyse the dependence of heat and mass transfer rates on fluid and system properties, and geometry.
3. Compare heat and mass transfer mechanisms and describe their analogies.
4. Solve problems involving heat and mass transfer, such as heat transfer between fluids in contact, radiation to/from surfaces, and heat and mass transfer coefficients.
5. Apply dimensional analysis to develop the correlations for heat and mass transfer.
6. Calculate overall heat transfer coefficient and heat transfer area of heat exchangers using LMTD and NTU methods.
7. Compare and report the experimental measurement of heat and mass transfer processes with the results from theory of heat and mass transfer, respectively.

### Assessment

Continuous internal assessment: 40%
Examination (3 hours): 60%

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.
