Pre-requisite: (MAT2500 and MEC2101) or Students must be enrolled in one of the following Programs: GCEN or GDET or METC or MEPR or GCNS or GDNS or MENS
Mechanical engineers are expected to have the knowledge and the understanding of the basic principles and concepts of fluid mechanics both in static and dynamic conditions. This is to enable them to analyse and design systems in which fluid is the working medium.
This course presents the fundamental concepts of fluid behaviour both under static and dynamic conditions. This course is designed to enable the student to analyse and design any practical systems in which fluid is the working medium. The content of this course includes statics and dynamics of fluid flow, dimensional analysis, internal viscous flow (eg laminar and turbulent flows in pipes and ducts), viscous flow around bodies, boundary layer and compressible flow.
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- estimate the forces on submerged bodies in static fluid situation;
- analyse the transportation of different types of fluids in a variety of applications and be able to avoid unwanted phenomena such as cavitation and water hammer;
- estimate the forces on moving, or stationary bodies caused by flowing fluids, either internally or externally such as forces on nozzles, elbows, blades and drag forces on chimneys, high rise buildings, different types of constructions, aircraft and ships;
- analyse the behaviour of high speed flows ie compressible flow in ducts, nozzles and diffusers.
Introduction and Fundamental Concepts
Definition of a fluid, dimensions, units and methods of analysis, fluid as a continuum, some basic definitions, description and classification of fluid motions.
Pressure variations in static fluid, hydrostatic forces on submerged bodies.
Control Volume Formulation
Basic equations for fluid flow, such as continuity, momentum and energy equations for control volume approach, and the angular momentum principle.
Differential Form Formulation
Differential form of the basic equations, Euler's and Bernoulli's equations.
Similitude and Dimensional Analysis
Buckingham's Pi theorem, important dimensionless groups, dynamic similarity practical use of the dimensionless groups.
Internal Incompressible Viscous Flow
Laminar and turbulent flows, pipe flow, head loss in pipes, minor head loss in pipe systems, hydraulic and energy grade lines, multiple path pipe systems.
External Incompressible Viscous Flow
Boundary layer, laminar and turbulent flow on flat plate fluid flow about immersed bodies, drag and lift forces.
Study compressible flow in changing area channels with or without friction.

- Student Administration will advise students of the dates of their examinations during the semester.
Important assessment information
It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.
Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an assessment item a student must achieve at least 50% of the marks or a grade of at least C-. Students do not have to satisfactorily complete each assessment item to be awarded a passing grade in this course. Refer to Statement 4 below for the requirements to receive a passing grade in this course.
Penalties for late submission of required work:
If students submit assignments after the due date without (prior) approval of the examiner then a penalty of 5% of the total marks gained by the student for the assignment may apply for each working day late up to ten working days at which time a mark of zero may be recorded. No assignments will be accepted after model answers have been posted.
Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade in a course a student must obtain at least 50% of the total weighted marks for the course.
Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course.
In a Restricted Examination, candidates are allowed access to specific materials during the examination. The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); Non-programmable calculator may be brought in to the examination (Students must note the make and model of the calculator used in the examination on the front of the answer book or examination paper where applicable); Formula sheet (A handwritten A4 sheet (two sides) containing any information that they believe will be relevant for the examination). Tables, charts and graphs needed for the solution of the examination will be provided.
Examination period when Deferred/Supplementary examinations will be held:
Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course.
University Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene University policies and practices. These policies can be found at http://policy.usq.edu.au.
The due date for an assignment is the date by which a student must despatch the assignment to the USQ. The onus is on the student to provide proof of the despatch date, if requested by the Examiner.
Students must retain a copy of each item submitted for assessment. This must be despatched to USQ within 24 hours if required by the Examiner.
In accordance with University Policy, the Examiner may grant an extension of the due date of an assignment in extenuating circumstances.
If electronic submission of assessments is specified for the course, students will be notified of this in the course Introductory Book and on the USQ Study Desk. All required electronic submission must be made through the Assignment Drop Box located on the USQ Study Desk for the course, unless directed otherwise by the examiner of the course. The due date for an electronically submitted assessment is the date by which a student must electronically submit the assignment. The assignment files must be submitted by 11.55pm on the due date using USQ time (as displayed on the clock on the course home page; that is, Australian Eastern Standard Time).
If the method of assessment submission is by written, typed or printed paper-based media students should (i) submit to the Faculty Office for students enrolled in the course in the on-campus mode, or (ii) mail to the USQ for students enrolled in the course in the external mode. The due date for the assessment is the date by which a student must (i) submit the assessment for students enrolled in the on-campus mode, or (ii) mail the assessment for students enrolled in the external mode.
The Faculty will NOT normally accept submission of assessments by facsimile or email.
Students who do not have regular access to postal services for the submission of paper-based assessments, or regular access to Internet services for electronic submission, or are otherwise disadvantaged by these regulations may be given special consideration. They should contact the examiner of the course to negotiate such special arrangements prior to the submission date.
Students who have undertaken all of the required assessments in a course but who have failed to meet some of the specified objectives of a course within the normally prescribed time may be awarded one of the temporary grades: IM (Incomplete - Make up), IS (Incomplete - Supplementary Examination) or ISM (Incomplete -Supplementary Examination and Make up). A temporary grade will only be awarded when, in the opinion of the examiner, a student will be able to achieve the remaining objectives of the course after a period of non directed personal study.
Students who, for medical, family/personal, or employment-related reasons, are unable to complete an assignment or to sit for an examination at the scheduled time may apply to defer an assessment in a course. Such a request must be accompanied by appropriate supporting documentation. One of the following temporary grades may be awarded IDS (Incomplete - Deferred Examination; IDM (Incomplete Deferred Make-up); IDB (Incomplete - Both Deferred Examination and Deferred Make-up).
Harvard (AGPS) is the referencing system required in this course. Students should use Harvard (AGPS) style in their assignments to format details of the information sources they have cited in their work. The Harvard (AGPS) style to be used is defined by the USQ Library's referencing guide. http://www.usq.edu.au/library/referencing
Students will require access to e-mail and internet access to UConnect for this course.
