Friday 1 pm
YOU ARE TO ATTEND TUTORIALS IN YOUR ENROLLED GROUP ONLY, and
YOU ARE STRONGLY URGED TO ATTEND ALL TUTORIALS WHERE INDIVIDUAL ATTENTION FROM H TUTORS IS AVAILABLE
Labs: refer SSO for your group and time:
LAB 1: ENERGY BALANCE & HEAT TRANSFER Wks 4, 5, 6 Room 402.211 MDLS Flexi-1
LAB 2: MOMENTUM OF AN AIR JET AND LOSSES IN PIPES Wks 7, 8, 9 Room 402.211 MDLS Flexi-1
Be careful entering the lab due to the construction work nearby. You should come from Grafton Road.
.
YOU MUST ATTEND BOTH LABS AT THE TIMES ADVISED FOR YOUR GROUP. IF YOU MISS A LAB, YOU WILL NOT BE ALLOWED TO ATTEND ANOTHER SESSION, except under exceptional circumstances.
Note:
This paper introduces many new concepts which you must understand, so the material does not lend itself to last-minute cramming for exams. Therefore, you are expected to:
1. Attend the tutorials; and
2. Devote at least 6 hours to this course each week, in addition to the 4 contact hours. You may spend such time towards reading material and examples from the text and then attempting problems from tutorial sheets and the text.
Handouts:
Lectures:
During each lecture week, you will be provided with a 1 or 2 page handout containing keywords and textbook section numbers for your reading. Lecture notes containing blanked-out sections will be posted on Canvas. You will need to bring either hard or electronic copies of these blanked out notes to the lectures to fill in during the lecture. Where possible, powerpoint presentations will be made available via Canvas.
Tutorials:
A tutorial sheet will be uploaded onto Canvas each week.
Laboratories:
Laboratory handouts will be uploaded onto Canvas in weeks 3, and 6 or before then.

Academic integrity
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting his or her learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the world-wide web. A student's assessed work may be reviewed against electronic source material using computerised detection mechanisms. Upon reasonable request, students may be required to provide an electronic version of their work for computerised review.
All students enrolled at the University of Auckland are required to complete a compulsory Academic Integrity course, usually in their first semester/year of enrolment. The University of Auckland’s full guidelines on procedures and penalties for academic dishonesty are available here.
Actions shared/based on previous feedback
Our feedback is that students like annotating lecture notes in this course, so we will continue with this mode of delivery.
Feedback is that taking notes and sketching diagrams helps student learning.
This site intends to guide you through your chosen specialisation at the Faculty of Engineering. The semester links lets you view detailed course information for your chosen course. Please note that the structure displayed for your specialisation here will reflect what’s available over the upcoming semesters, but detailed information may be from a previous year.
All the information here is accurate at the time of publication, but you are are advised to additionally consult our official document, the University of Auckland Calendar, for accurate academic regulations, requirements, and policies.
