We are aiming for an incremental return to campus in accordance with guidelines provided by NSW Health and the Australian Government. Until this time, learning activities and assessments will be planned and scheduled for online delivery where possible, and unit-specific details about face-to-face teaching will be provided on Canvas as the opportunities for face-to-face learning become clear.

Unit of study_

CHNG9203: Heat and Mass Transfer

CHNG2803/9203 is a practically and theoretically-based course, where students will be introduced to types of problems that the modern chemical engineer may be asked to solve. The material is contemporary in nature, and the projects link with the key concepts taught in CHNG2801/9201 and CHNG2802/9202 and across the curriculum. The objectives in this unit are to provide an interesting, enjoyable, and challenging introduction to fundamental aspects of chemical engineering, particularly conservation and transport processes involving fluids and energy, as well as to the application of mathematical techniques in typical engineering problems. In this course there is one overall project. The overall goal of the project work throughout this semester is to build a small cooling tower. This cooling tower may be used to cool water from processes that make the water hot, to humidify air that is cold and dry (as in a Sydney winter) or to dehumidify warm wet air (as in a Sydney summer). The overall project will be split into two sub-projects: Fluid mechanics- 4 weeks; Heat and mass transfer- 8 weeks. The project in CHNG9203 addresses transport processes, including the movement of momentum (fluid mechanics), thermal energy (heat transfer) and components with mass. The projects are underpinned by a critical and constructive analysis and best practice in learning and teaching. In addition to the basic knowledge and skills required to pass this unit, the development of an understanding sufficient to enable you to tackle new and unfamiliar problems will be emphasized. You will learn to work in largely unsupervised groups and to be responsible for managing your individual and group performance.

For more information see sydney.edu.au/students/guide-to-grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Special consideration

If you experience short-term circumstances beyond your control, such as illness, injury or misadventure or if you have essential commitments which impact your preparation or performance in an assessment, you may be eligible for special consideration or special arrangements.

Academic integrity

The Current Student website provides information on academic honesty, academic dishonesty, and the resources available to all students.

The University expects students and staff to act ethically and honestly and will treat all allegations of academic dishonesty or plagiarism seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic dishonesty. If such matches indicate evidence of plagiarism or other forms of dishonesty, your teacher is required to report your work for further investigation.

Attendance and class requirements

Students must attend lectures, tutorials and lab sessions. Attendance may be taken regularly.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.
