Co-Requisites: CHEM2404 AND CHNG2801 AND CHNG2802.
Brief Handbook Description: This unit of study is centred around three real-life engineering projects which cover traditional and non-traditional domains of chemical engineering, and span the energy, chemical processing and bio-medical sectors. By the end of this unit, students will be proficient in analysing complex fluid and energy networks and decomposing them into their essential component parts. Students will understand the functionality of each of these key components, and will be able to characterise the performance of the engineering network in terms of both component and system-wide variables. Students will also be able to take this information and explore the optimum operating conditions for the network. This unit of study runs concurrently with two enabling technology units of study, CHNG2801 and CHNG2802. These two units will provide students with the tools and know-how to tackle the real-life engineering problems encountered in CHNG2803. This integrated course structure is designed to help students become familiar with the multi-disciplinary nature of chemical engineering today.
Assumed Knowledge: Ability to conduct mass and energy balances, and the integration of these concepts to solve real chemical engineering problems 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.

Assessment Description: You are technical consultant working for a large investment firm. The firm has identified an opportunity to produce absorption cycle air conditioners for Sydney, which is experiencing more frequent brownouts and blackouts in different parts of the city, particularly at peak temperatures during the day. The firm seeks more information before proceeding further.

Your particular group must provide an overall evaluation of the engineering technology required for air conditioners using this type of cycle, with a final recommendation for your firm. In particular, the firm asks you to estimate the requirements for producing these air conditioners. Your group’s evaluation should include a technical evaluation of the technology, and you should also address ethical and social considerations (what implications does this investment possess for your firm?) - details below.

Specifically you must build up a final report in the following stages:

Interim report, fluid mechanics: 3 pm, Friday, 1 April (week 5) (15% of project)

Interim report, heat transfer: 3 pm, Wednesday, 20 April (week 8) (15% of project)

Final written report hand in: 3 pm Friday, 27 May (week 12) (70% of project)

Self and peer assessments: 4 pm, Friday, 27 May (week 12)

Interviews: Monday, 30 May, and Wednesday, 1 June, sometime in the 2-5 pm time slots

The final report will need to reconsider the physical sizes and dimensions required for the pipes, and the arrangement of the tank and column. You must also detail your assumptions and any uncertainties, and their impacts on your assessment.

Self/peer assessments and interviews are conducted following submission of the final report in order to evaluate individual contributions to group project work.
Grade Type Description
Standards Based Assessment Final grades in this unit are awarded at levels of HD for High Distinction, DI (previously D) for Distinction, CR for Credit, PS (previously P) for Pass and FA (previously F) for Fail as defined by University of Sydney Assessment Policy. Details of the Assessment Policy are available on the Policies website at . Standards for grades in individual assessment tasks and the summative method for obtaining a final mark in the unit will be set out in a marking guide supplied by the unit coordinator.
