Unit of study_

# MECH3261: Fluid Mechanics 2

## Overview

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.

### Assessment summary

• 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.

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.

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.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

## 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.

### 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 be recorded. The Faculty of Engineering and IT has a policy that students attend 90 percent of timetabled activities for a unit of study http://sydney.edu.au/handbooks/engineering/general/faculty_resolutions.shtml. To support this policy, weekly online quick quizzes will be held. 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

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.

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.
