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 CHNG2801 (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: It is assumed that students will be concurrently enrolled in or have already completed: CHNG2801 or equivalent, and (CHNG2802 or MATH2xxx)
