This module covers the critical theoretical material for mass and heat transfer. It extends the introductory material taught in Introduction to Transport Phenomena and Thermodynamics. This includes a general energy balance for conduction and common simplifications for symmetrical 2-D and 1D problems. The lumped capacitance method is discussed as well as heat transfer from extended surfaces. Engineering processes such as membrane separations and adsorption are described. In addition, the critical theoretical material for momentum transport is discussed and addresses viscous and turbulent flows between solid boundaries. The principle of similitude is applied to the design and analysis of pumped flow systems and cost optimisation is applied to the design of pipelines. Engineering applications such as complex pipe networks and combined pipe-pump systems are analysed. The heat transfer material covered is further extended to cover internal/external convection and radiation. Computer based methods of solution of heat and mass transfer problems are introduced and applied to some process examples. Typical content would include: Use of lumped capacitance method to calculate temperature distributions and heat flux in transient cooling/heating problems; Simplified general energy balance to describe specific problems (2D or 1D simplifications) and definition of appropriate initial/boundary conditions; Calculation of heat flux from finned surfaces
