For the purposes of considering applications for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005) and Students Experiencing Academic Disadvantage Policy, this subject requires all students to actively and safely participate in laboratory activities. Students who feel their disability may impact upon their participation are encouraged to discuss this with the Subject Co-ordinator and the Disability Liaison Unit http://www.services.unimelb.edu.au/disability/

The fundamental concepts of heat transfer are extended from that covered in earlier subjects to include natural and forced convection and two phase systems. Mass transfer concepts are extended to unsteady state mass transfer and Fick's Second Law, prediction of diffusivity and of mass transfer coefficients. These fundamental concepts are then applied to the design of processes and equipment including shell and tube, air-cooled and plate heat exchangers, evaporator systems, membrane devices, binary distillation systems, gas absorbers and cooling towers. Use of appropriate simulation packages such as HYSYS and ASPEN will be included.

On completion of this subject students should be able to:

• Apply the principles of heat transfer to solve heat transfer problems, particularly those involving two phase systems
• Assess quantitatively the performance of heat exchanger and evaporation equipment
• Apply the principles of mass transfer to solve mass transfer problems and to membrane separation processes
• Describe the concepts of equilibrium stage and continuous contactor analysis and apply these concepts to simple distillation and gas absorption problems
• Assess quantitatively the performance of simple, conventional distillation, gas absorption and cooling tower equipment
• Use simulation software for the basic design of heat exchangers and distillation columns

• A written 3-hour end-of-semester examination (70%)
• A 90-minute written class test one third of the way through the semester (15%)
• Assignments involving laboratory work expected to take about 10 hours due during the semester (15%)
• A mark of greater than 40% in the end-of-semester examination is required to pass the subject
