INTRODUCTION

Dear Student 1.1

Tutorial matter

I am pleased to welcome you to this module (FMC2601 – Fluid Mechanics II) and hope that you will find it both interesting and rewarding. You will be well on your way to success if you start studying early in the semester/ year and resolve to attempt both the tutorial questions as well as assignment(s) properly. The assignment(s) will be graded and will constitute a certain percentage towards to the final module grade. You may receive a number of tutorial letters during the year. A tutorial letter is our way of communicating with you about teaching, learning and assessment. Tutorial Letter 101 contains important information about the scheme of work, resources and assignments for this module. We urge you to read it carefully and to keep it at hand when working through the study material, preparing the assignment(s), preparing for the examination and addressing questions to your lecturers. Please read Tutorial Letter 301 (not all modules have this document) in combination with Tutorial Letter 101 as it gives you an idea of generally important information when studying at a distance and within a particular College. In Tutorial Letter 101, you will find the tutorial questions, assignments and assessment criteria as well as instructions on the preparation and submission of the assignments. It will also provide all the information you need with regard to the prescribed study material and other resources and how to obtain it. Please study this information carefully and make sure that you obtain the prescribed material as soon as possible. General and administrative information about this module can also be found in this tutorial letter. Please study this section of the tutorial letter carefully. I would like to point out that you must read all the tutorial letters you receive during the semester immediately and carefully, as they always contain important and, sometimes, urgent information. Some of this tutorial matter may not be available when you register. Tutorial matter that is not available when you register will be posted to you as soon as possible, but is also available on myUnisa. I hope that you will enjoy this module and wish you all the best!

PURPOSE OF AND OUTCOMES FOR THE MODULE

2.1

Purpose

This module is a 12-credit module, and is an introduction to the field (equivalent to the National Quality Framework level 5) of fluid mechanics. This module is part of the qualification, Diploma in Engineering: Mechanical.

3

Fluid mechanics is an essential part of mechanical engineering and are essential for you, who will be pursuing a career in engineering after graduation. 2.2

Outcomes

FMC2601 is the first or a number of modules in fluid mechanics and seeks to achieve the following purpose and outcomes: 1. Introduction to basic terminologies used in fluid mechanics 2. Introduction and understanding of fluid properties 3. Concepts of fluid statics (i.e. what happens when fluids are not flowing) 4. Buoyancy of objects in fluids and stability when floating 5. Concepts of fluid dynamics (i.e. what happens when fluids are flowing) 6. Flow measurement techniques and equipment 7. Other related concepts At the end of the module, you should be able to adequately perform calculations and/or determine the forces, properties, and flow in the above stated concepts.

STUDENT SUPPORT SERVICES

The Study @ Unisa brochure is available on myUnisa: www.unisa.ac.za/brochures/studies For information on the various student support systems and services available at Unisa (e.g. student counselling, tutorial classes, language support), please consult the publication my Studies @ Unisa that you received with your study material. 6

FMC2601/101/3/2019

This brochure has all the tips and information you need to succeed at distance learning and, specifically, at Unisa. Contact with fellow students Study Groups It is advisable to have contact with fellow students. One way to do this is to form study groups. The addresses of students in your area may be obtained from the following department: Directorate: Student Administration and Registration PO Box 392 UNISA 0003 MyUnisa You can quickly access resources and information at the University through the myUnisa portal. The myUnisa learning management system is Unisa's online campus that will help you to communicate with your lecturers, with other students and with the administrative departments of Unisa – all through the computer and the internet. To go to the myUnisa website, start at the main Unisa website, http://www.unisa.ac.za, and then click on the “Login to myUnisa” link on the right-hand side of the screen. This should take you to the myUnisa website. You can also go there directly by typing in http://my.unisa.ac.za. Please consult the publication my Studies @ Unisa which you received with your study material for more information on myUnisa. Discussion / Contact Sessions Discussion or contact sessions may be scheduled at the request of students, or at the discretion of the lecturer. If you wish to initiate such a session, please gather at least 5 students and propose to your lecturer. Tutorials You will find a list of tutorial questions at the back of this tutorial letter but problems in the prescribed textbook and recommended reading can be used as tutorials in addition. The memorandum to the tutorial questions will be released periodically on myUnisa and on demand but they do not require submission and also do not constitute to the final mark. Videoconferencing As UNISA is going online, regular once a month videoconferencing discussion classes will be held for this module. The software used will be Teamviewer. Exact schedule of these sessions will be posted on myUnisa in due time. You can download the software at www.teamviewer.com/en/index.aspx. Here is a youtube video on attending meetings using this software. https://www.youtube.com/watch?v=1BwqK8YMQM0.

STUDY PLAN

The module can largely be broken up into a few subsections and can be studied in a modular approach. The following lists the subsections: 1. Basic terminologies and fluid properties (Chapter 1) 2. Fluid statics and hydrostatic forces (Chapter 2, 3, 5) 3. Buoyancy (Chapter 4) 4. Fluid dynamics (Chapter 6) 5. Fluid flow in pipes (Chapter 7) 6. Flow measurement techniques and equipment (Chapter 8) Consistent work is important to the successful study of this module (and all other modules at UNISA). Queries from earlier chapters must be clarified as soon as possible instead of “leaving it to the end”. As concepts often cut across subsections, these queries can accumulate into a large problem if unattended to. In addition to the prescribed and recommended textbooks, you should look for additional textbooks. However as some textbooks may contain outdated information or concepts, it’s better to search for one in which the latest edition was published not more than 10 years ago. Use your my Studies @ Unisa brochure for general time management and planning skills.

PRACTICAL WORK

There are no practicals for this module. The practical work for this module is in another separate module titled FMCPRA2. You must also register for that module as part of your diploma program. Both this module as well as FMCPRA2 may be required as pre-requisite for more advanced courses of your diploma program.

ASSESSMENT

8.1

Assessment criteria

The mark for Fluid Mechanics II (FMC2601) is calculated as follows: The year mark contributes to 20% of final mark and is calculated: Year Mark = (Assignment 1 x 0.4) + (Assignment 2 x 0.6). The examination mark contributes to 80% of the final mark 8.2

Assessment plan

The overall assessment consists of two parts, assignments (also known as class tests in traditional contact universities) and examinations. In addition, there are also a set of tutorial questions (and memorandum), which is to be completed in order to help you pass your module. These tutorials do not need to be submitted and do not constitute to the final module mark but they MUST be attempted. You are free to ask me questions should you have problems understanding the memorandum for them. Please note that attempting only the assignments will not enable you to pass the final exam. 8

FMC2601/101/3/2019 Assignments will not have memorandum released to you as they play the role of class tests. Note that the scope of the assignments will not be as wide as the final exams and it is imperative that you go through the tutorials and also questions in the book.

Submission of assignments

Assignments are seen as part of the learning material for this module. As you do the assignments, study the reading texts, consult other resources, discuss the work with fellow students or tutors or do research, you are actively engaged in learning. Looking at the assessment criteria given for each assignment will help you to understand what is required of you more clearly. In some cas...
