MECH3261: Fluid Mechanics 2

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.

  • Homework assignments: Fortnightly assignments will be set. The six assignments are worth 1% each.
  • Lab report: A two hour laboratory is part of this course and is worth 8% of the total mark. 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.
  • 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.

Detailed information for each assessment can be found on Canvas.

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


High distinction

85 - 100



75 - 84



65 - 74



50 - 64



0 - 49

When you don’t meet the learning outcomes of the unit to a satisfactory standard.

Important note:  There are two criteria for passing this course. You must get at least 50% overall and at least 45% in the final exam.

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.

This unit has an exception to the standard University policy or supplementary information has been provided by the unit coordinator. This information is displayed below:

Homework 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.

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

Lectures: These introduce the key concepts and provide derivations of the analytical methods for fluid flows. Many worked examples are provided. Lectures will given online via Zoom and will be recorded. Questions and discussion are encouraged during MECH3261 lectures.

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.

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.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University’s graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. determine the appropriate flow and geometrical parameters of pumps, channels and piping systems in order to be able to design real world fluid systems
  • LO2. solve fluid mechanics problems related to pipe, pump and channel flows; lift and drag on immersed bodies such as wings; boundary layer theory and application; gas dynamics in compressible systems
  • LO3. simplify fundamental theory in order to use it in the analysis of real-world pipe flow, boundary-layer flow, lift and drag calculations, and gas dynamics calculations
  • LO4. recognise and identify fundamental aspects of a wide range of fluid flows through derivation, use and manipulation of the Navier-Stokes equations.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1 Depth of disciplinary expertise

Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.

GQ2 Critical thinking and problem solving

Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.

GQ3 Oral and written communication

Effective communication, in both oral and written form, is the clear exchange of meaning in a manner that is appropriate to audience and context.

GQ4 Information and digital literacy

Information and digital literacy is the ability to locate, interpret, evaluate, manage, adapt, integrate, create and convey information using appropriate resources, tools and strategies.

GQ5 Inventiveness

Generating novel ideas and solutions.

GQ6 Cultural competence

Cultural Competence is the ability to actively, ethically, respectfully, and successfully engage across and between cultures. In the Australian context, this includes and celebrates Aboriginal and Torres Strait Islander cultures, knowledge systems, and a mature understanding of contemporary issues.

GQ7 Interdisciplinary effectiveness

Interdisciplinary effectiveness is the integration and synthesis of multiple viewpoints and practices, working effectively across disciplinary boundaries.
