CHNG9203: Heat and Mass Transfer

Semester 1, 2023 [Normal day] - Camperdown/Darlington, Sydney

Overview

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.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100
Distinction	75 - 84
Credit	65 - 74
Pass	50 - 64
Fail	0 - 49	When you don’t meet the learning outcomes of the unit to a satisfactory standard.

For more information see 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.

Academic integrity

The Current Student website provides information on academic integrity 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 integrity breaches seriously.

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

Use of generative artificial intelligence (AI) and automated writing tools

You may only use generative AI and automated writing tools in assessment tasks if you are permitted to by your unit coordinator. If you do use these tools, you must acknowledge this in your work, either in a footnote or an acknowledgement section. The assessment instructions or unit outline will give guidance of the types of tools that are permitted and how the tools should be used.

Your final submitted work must be your own, original work. You must acknowledge any use of generative AI tools that have been used in the assessment, and any material that forms part of your submission must be appropriately referenced. For guidance on how to acknowledge the use of AI, please refer to the AI in Education Canvas site.

The unapproved use of these tools or unacknowledged use will be considered a breach of the Academic Integrity Policy and penalties may apply.

Studiosity is permitted unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission as detailed on the Learning Hub’s Canvas page.

Outside assessment tasks, generative AI tools may be used to support your learning. The AI in Education Canvas site contains a number of productive ways that students are using AI to improve their learning.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.
