Paper Description

Edit Paper Description Content

This course covers the basic principles of fluid mechanics. Topics include fluid statics, fluid dynamics, Bernoulli and energy equations, momentum analysis of flow structures, flow measurement, dimensional analysis, internal flow in pipes and ducts, external flow over streamlined and bluffed bodies, pump sizing and selection, and an introduction to open channel flow.

Paper Structure

Edit Paper Structure Content

The paper content is delivered through a combination of online mini-lectures, face-to-face lecture/tutorial combinations (called 'Lectorial'), face-to-face laboratories and workshops, and face-to-face tutorial (additional for students who are struggling).

Please note that the 'lectorials' start in the first week of the trimester, laboratories, and special help tutorial start in the second week , the Bottle Rocket challenge workshops start in the fourth week. All of these activities are an essential part of the learning for this paper.

Learning Outcomes

Edit Learning Outcomes Content

Students who successfully complete the course should be able to:

  • Explain in scientific terms the basic properties of fluids, including viscosity, surface tension, and pressure.
    Linked to the following assessments:
  • Explain in scientific terms the underlying principles and mechanisms that govern the behaviour and motion of fluids in internal and external flows.
    Linked to the following assessments:
  • Apply dimensional analysis principles to fluid modelling of real world situations.
    Linked to the following assessments:
  • Solve practical fluid problems that engineers are likely to face in the real world.

    These include:

    • application of Newton’s law of viscosity to shearing surfaces,
    • pressure measurement with manometers,
    • hydrostatics to submerged surfaces,
    • the application of the Bernoulli equation to mechanical energy processes,
    • linear and angular momentum,
    • pipe friction loss,
    • pump sizing,
    • drag and lift calculations,
    • turbomachinery,
    • open channel flow calculations.

Assessment

Edit Assessments Content

The learning outcomes are assessed using a combination of:

Assignments (20%)

Five assignments form an important part of the learning of the paper. Assignment problems allow you to practice important concepts, and therefore help cement your knowledge as well as prepare for the tests and exam. There will be a total of five assignments over the semester which will be released via Moodle. Do not copy from a class mate. Where copying is detected both scripts will get ZERO for the assignment. Do your own work.

Laboratories (15%)

There are a total of four laboratory worksheets to complete plus one practice report and one formal report that will be marked.

Test 1 (15%) - 2 hour

There will be an open book face-to-face test after 5 weeks. The test is worth 15% of your final grade. The date is shown below. The format will be discussed in class prior to the test. If you are taking the paper remotely then you will have the option to apply to take the test remotely. Please notify the convener that you will be taking the paper online.

Bottle Rocket Challenge (20%)

From the 3 Aug (week 4) to the 21 Sept (week 9) each laboratory group will design and build a bottle rocket and launch pad that is powered by a maximum air pressure of 60 psi and a maximum water volume of 1 litre. The rocket that travels the furtherest horizontal distance will be the winner (10%). Each student is to submit a set of photographs and calculations that model the flight of the rocket (10%).

Test 2 (30%) - 3 hour

The final Test, held during Examination weeks, will cover the whole semester’s lecture material. It will be a open book face-to-face test. Programmable calculators, not containing stored information, are allowed.

The format of the final Test will be discussed in lectures during the last week of the course.

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0. There is no final exam. The final exam makes up 0% of the overall mark.

The internal assessment/exam ratio (as stated in the University Calendar) is 100:0 or 0:0, whichever is more favourable for the student. The final exam makes up either 0% or 0% of the overall mark.
