Download UoS Outline

Unit: CHNG9201: Fluid Mechanics (6 CP)
Mode: Normal-Day
On Offer: Yes
Level: Postgraduate
Faculty/School: School of Chemical and Biomolecular Engineering
Unit Coordinator/s: Prof Langrish, Timothy
Session options: Semester 1
Versions for this Unit:
Campus: Camperdown/Darlington
Pre-Requisites: None.
Prohibitions: CHNG9201 OR CHNG2801.
Brief Handbook Description: This unit of study is designed for postgraduate students who should be proficient at applying the basic principles of mass, energy and momentum balances to solve advanced engineering problems involving fluid statics and fluid mechanics. Further, students will be able to perform simple dimensional analysis and to see the utility of this general approach in engineering: for example in Reynolds numbers, friction factors, Bernoulli's equation, piping calculations, and pumps. The focus of this unit of study is to provide the key concepts and principles as tools through keynote lectures, with supporting tutorials and laboratory sessions giving valuable hands-on experience. Guidance will be provided to students to seek additional detailed information for specific applications in their projects. This unit of study runs concurrently with other enabling technology units of study, CHNG9202 in advanced mathematics, numerical analysis and statistics, and CHNG9203, heat and mass transfer. This integrated course structure is designed to help students become familiar with the multi-disciplinary nature of chemical engineering today.
Assumed Knowledge: Calculus, Computations (Matlab, Excel), Mass and Energy Balances.

# Activity Name Hours per Week Sessions per Week Weeks per Semester
1 Lecture 2.00 2 13
2 Tutorial 2.00 2 13
3 Independent Study 2.00 1 13
4 Laboratory 3.00 1 2
5 Presentation 4.00 1 1
T&L Activities: Tutorial: After each lecture, there will be a two hour tutorial. Students will solve various problems relevant to the topics of the lecture.

Independent Study: Students are expected to spend about 3-4 hours of ‘self directed learning’ outside the specified contact periods.

Laboratory: Groups will be allocated in week 4. Each group will conduct 2 experiments. The report should be submitted after two weeks.There will be oral presentation for one of the experiment.

Presentation: Each group will present the outcomes of their research and experimental work. It is expected that each group conduct a critical thinking and analyse the data acquired from the experiments and discuss the errors.

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.
