Unit: MECH9261: Fluid Mechanics 2 (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: School of Aerospace, Mechanical & Mechatronic Engineering
Unit Coordinator/s: Associate Professor Cleary, Matthew
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: AMME9261 AND AMME9262.
Prohibitions: MECH8261
Brief Handbook Description: This unit aims to provide students with a detailed understanding of the theory and practice of fluid mechanics in the context of mechanical engineering. Students will gain skills in problem solving in areas of pipe, pump and channel flow; lift and drag on immersed bodies; boundary layer theory and gas dynamics.

At the end of this unit students will have the ability to critically assess and solve problems commonly found in fluid mechanics practice, such as sizing pumps and piping systems, designing channels, and determing the lift and drag characteristics of submerged bodies. Additionally, they will develop a structured and systematic approach to problem solving.
Assumed Knowledge: None.

4 Independent Study 4.00 1 13
T&L Activities: Lectures: These introduce the key concepts and provide derivations of the analytical methods for fluid flows. Many worked examples are provided. Lectures will be recorded. Note however that the Faculty of Engineering and IT has a policy that students attend 90 percent of timetabled activities for a unit of study Lectures are a critical part of creating a vibrant learning environment and all students benefit from being part of an engaged group of learners. Questions and discussion are encouraged during MECH3261 lectures. Lecture recordings will be switched off if lecture attendance falls below about 50% of enrolled students.

Tutorial: There are two tutorial sessions per week. A set of homework problems are designated for each week. Marks will be given based on the completion of the fortnightly homework problems. It is your responsibility to check with the tutors to ensure that your solution is correct.

Quizzes: The material covered in lectures and tutorials will be examined via three quizzes.

Laboratory: A two hour laboratory is part of this course. Laboratory notes will be provided prior to the lab. The laboratory provides students with hands-on experience in data collection.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Assessment Description: * indicates an assessment task which must be repeated if a student misses it due to special consideration

Quiz: Three quizzes will be set, each worth 10% of the total mark. These will be held in the Monday 1 - 2 pm in weeks 6, 9 and 12.

Homework assignments: Fortnightly assignments will be set. The six assignments are worth 2% each. They are required to be handed in during the Friday tutorial on Weeks 3,5,7,9,11,13.

Lab Report: A two hour laboratory is part of this course and is worth 8% of the total mark. Laboratory notes are available on the course Canvas website. The laboratory covers the growth of boundary layers and the determination of lift and drag forces using manometer readings. The lab report tests understanding of concepts presented in the lectures over weeks 1-8. The lab is held in weeks 5,6,7 and 8. The lab report is due in week 10 on Friday at 5pm. The lab report must be submitted through the course Canvas Site. Text-based similarity detecting software (Turnitin) will be used to detect plagiarism.

Final Exam: A two hour exam will be conducted in the exam period and is worth 50% of the total mark. You must get 45% in the final exam to pass the unit, regardless of the sum of your individual marks.

Late submission: Assignments are due during tutorial sessions and may not be submitted at any other time. Following a philosophy of rapid dissemination of feedback, worked solutions to labs will be provided immediately after the lab report due date. Therefore late submission of lab reports will not be accepted and will receive a mark of zero.
