Notice
As part of Phase 3 of our return to campus plan, most units will now run tutorials, seminars and other small group learning activities on campus for the second half-year, while keeping an online version available for those students unable to return or those who choose to continue their studies online.
To check the availability of face to face activities for your unit, please go to timetable viewer. To check detailed information on unit assessments visit your unit's iLearn space or consult your unit convenor.

Unit description |
Unit description
This unit examines the principles of heat and mass transfer. The unit covers knowledge in theories related to the analysis of different heat transfer modes such as conduction, convection, and radiation. At the end of the unit, students are expected to demonstrate the ability to apply the principles of heat and mass transfer to analyse local and overall heat and mass transfer coefficients and to design experiments to improve existing heat and mass transfer engineering systems. |
Information about important academic dates including deadlines for withdrawing from units are available at https://www.mq.edu.au/study/calendar-of-dates
On successful completion of this unit, you will be able to:
In order to pass this unit a student must obtain a mark of 50 or more for the unit (i.e. obtain a passing grade P/ CR/ D/ HD). There are no hurdle assessments.
The following conditions apply for all assessments:
For assignments handed in late the following penalties apply: 0-24hrs -25%, 24-48hrs -50%, greater than 48hrs -100%.
All assessments will be graded according to standards set in the marking rubrics. Students will receive a numerical grade for each assessment which will be representative of a fail (0-49%), pass (50-64%), credit (65-74%), distinction (75-84%) or high distinction (85-100%) as defined by the university standards based assessment guidelines. The definitions of these standards will be posted on the iLearn page. All marking rubrics specific to each assessment will be released on the iLearn page clearly indicating requirements to achieve a particular standard. These will be released well in advance of the assessment due date or are specified below.
Weekly Quiz (10/100)
Each tutorial will typically consist of 4 questions. In addition, students will also receive 1 tutorial question as a weekly quiz . Students must individually attempt the weekly quiz and submit the answer on iLearn by the Friday of that week. The tutor will allocate either a fail grade for incorrect methodology and incorrect answer, a pass grade for sound methodology but incorrect answer, or up to a high distinction grade for sound methodology and correct answer. A maximum of 1 mark (out of 100 available for the unit) is available for each of the tutorial sessions from weeks 3-7 and 9-13.
Assignments (10/100)
Assignment 1: (5/100)
This individually marked assignment will test the student’s ability to apply and critically interpret the course material related to introductory concepts in heat transfer by conduction. The assignment will involve a combination of analytical calculations, design and report writing. A rubric will be provided with the assessment handout.
Assignment 2: (5/100)
This individually marked assignment will test the student’s ability to conceptually design an experimental system for heat convection. The student will design a system based on analytical calculations, whilst making considerations for suitable equipment, develop a series of theoretical results and suggest methods of experimental improvement. A rubric will be provided with the assessment handout.
Practical Laboratory Sessions (15/100)
Two individual lab reports written for two unique experiments. Attendance will be taken at the practical sessions. Students must be present in order to submit a lab report. The location of the practical sessions will be in 13RPD (F9C) 110. Precise details on time will be advised via the iLearn page. Both laboratory reports will be assessed according to a rubric to be made available on the iLearn page.
Laboratory Report 1: (7/100)
The first experiment will demonstrate the operation of heat exchangers. Students will test a particular heat exchanger design, acquire data, and compare to theoretical calculations of heat exchanger performance. A laboratory report is then handed in.
Laboratory Report 2: (8/100)
The second experiment will demonstrate experimental techniques used to take measurements of conduction and convection. The data collected will be presented and interpreted along with some theoretical calculations. A laboratory report is then handed in.
Mid Session & Final Examinations (65/100)
Mid-Session Test: (15/100)
An in-class 1hr test assessing material delivered between weeks 1 and 6.
Final Examination: (50/100)
A final examination (3hrs) assessing all material (weeks 1-13) delivered throughout the unit.
If you receive special consideration for the final exam, a supplementary exam will be scheduled in December 2019. By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. Approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.
