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, turbomachinery and an introduction to compressible flow.

Paper Structure

Edit Paper Structure Content

The paper content is delivered through a combination of online mini-lectures, face-to-face lectures, face-to-face laboratories and workshops, and face-to-face tutorials.

Please note that the Lectures and Tutorials start in the first week of the trimester (starting from Tuesday), laboratories start in the second week, the Water Rocket challenge workshops start in the fifth week. All of these activities are an essential part of the learning for this paper.

Assessment

Edit Assessments Content

The learning outcomes are assessed using a combination of:

In class Quizzes (5%)

There will be six bi-weekly quizzes starting week 2 in the Thursday lecture. Only students attending the lecture will be able to sit the quiz. The best of five quizzes will be used toward your grade.

Laboratory Assignments (20%)

There will be five laboratory assignments worth 4% each.

Test (15%) - 2 hour

There will be a 2 hour face-to-face test in the PWC on Tuesday 7 Sept 6 - 8 pm. The format will be discussed in class prior to the test. You may bring 1 x A4 sheet written on both sides into the test.

Water Rocket Challenge (10%)

Starting from the 9 Aug (week 5) each laboratory group will design and build a water rocket that is powered by a maximum air pressure of 60 psi. The rocket that travels the furthest horizontal distance and can land the closest to a target will be the winner (5%). Each student is also required to submit a brief report along with an excel spreadsheet model of the flight of the rocket (5%).

Exam (50%) - 3 hour

The final Exam will be face-to-face and closed book. Programmable calculators, not containing stored information, are allowed. A formula sheet will be provided. The format of the Exam will be discussed in the tutorials during the last week of the course. Students must get a minimum of 40% in the exam to pass the paper.
