Site(s) for this Unit: http://canvas.sydney.edu.au/
Campus: Camperdown/Darlington
Pre-Requisites: None.
Prohibitions: CHNG2803 OR CHNG5703.
Brief Handbook Description: This unit of study teaches principles of heat and mass transfer required for chemical and biomolecular engineering. It covers steady and transient conduction and diffusion, convective transport of heat and mass, and radiative heat transfer.

It runs concurrently with CHNG9201 (Fluid Mechanics) to provide students with the tools and know-how to tackle engineering problems related to transport phenomena.

This unit of study also includes a project-based study component on heat and mass transfer phenomena in biological systems and two lab sessions on heat transfer equipment.

Students will develop a physical understanding of the underlying phenomena and gain the ability to solve real heat and mass transfer problems of engineering significance.
Assumed Knowledge: Ability to understand basic principles of physical chemistry, physics and mechanics. Ability to use mathematics of calculus (including vector calculus) and linear algebra, and carry out computations with MATLAB and MS EXCEL. Ability to read widely outside of the technical literature, and to synthesise arguments based on such literature. Ability to write coherent reports and essays based on qualitative and quantitative information
