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.

The learning outcomes for this paper are linked to Washington Accord graduate attributes WA1-WA11. Explanation of the graduate attributes can be found at: https://www.ieagreements.org/assets/Uploads/Documents/IEA-Graduate-Attributes-and-Professional-Competencies-2021.1-Sept-2021.pdf

Assessment

Edit Assessments Content

Samples of your work may be required as part of the Engineering New Zealand accreditation process for BE(Hons) degrees. Any samples taken will have the student name and ID redacted. If you do not want samples of your work collected then please email the engineering administrator, Natalie Shaw (natalie.shaw@waikato.ac.nz), to opt out.The learning outcomes are assessed using a combination of:

Tutorial Assignments (10%)

There will be five tutorial assignments worth 2% each.

Laboratory Assignments (15%)

There will be five laboratory assignments worth 3% each.

Test (15%) - 2 hour

There will be a 2 hour face-to-face test in the LG.01 on Tuesday 13 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 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 (2.5%) and can land the closest to a target (2.5%) will be the winner. Each student is also required to submit a brief report along with an excel spreadsheet model of the flight of the rocket (5%). The launch competition will be held on Monday 10 Oct from 9am - 12noon on the university field near the Swimming Pool.

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.
