2. MODULE LEARNING OUTCOMES
This module will be presented according to the outcomes-based education philosophy.
The lecturer will use a variety of instructional techniques and methods in striving towards
achieving the critical cross-field outcomes as well as the general aims of the module and
the specific outcomes.
2.1
Calculation of Module Credits and Notional Hours
The minimum notional hours required by a student for successful completion of this
module, as well as the credits allocated to the module, are calculated from the formula
supplied by HESQSF (Refer to ECSA document E-01-P and E-24-STA):
Notional Hours = W (LTLML + tTTMT) + PTPMP + X + ATA
Credits = Notional Hours / 10
Where W is the number of weeks per semester, L and t the number of online lecturing and
tutorial periods per week respectively, P is the total number of practicals (virtual or
conducted on campus) and A the number of assignments per semester. X is the number
of self-study content and TX duration of completing the self-study content in hours. Then
TL, TT, TP and TA are the duration of a lecturing period, a tutorial period, a practical period
and an assignment in hours, respectively, while ML, MT and MP represents a work factor
for lectures, tutorials and practicals respectively.
The blended learning notional hours and associated credits for Hydrodynamic Machines
III, together with an explanation of the work factors, are calculated below:

3. LEARNING COMPONENT
3.1
Guidelines for improving performance in the module
Attend all classes. Prepare for each lecture by using this learning guide. Unless you ask
questions, the lecturer will assume that you understand all the theory and will commence
with applications. If you do not understand, bring it to the lecturer’s attention as soon as
possible by asking specific questions.
During the years, it has been proven that the following guidelines will result in academic
success:
• Read the appropriate section in your learner guide carefully before attending
the lecture.
• You should study the completed section in depth, as soon as possible after the
lecture, but at least before the following lecture.
• You must complete all the relevant homework exercises, assignments or
questions for each lecture topic. Spend more time thinking about the problem
and referring to resources mentioned in the learning units. Try to answer the
question to the best of your ability. If you have made any mistake, small as it
may be, correct it in class and if you are still not sure about the solution, ask the
lecturer for further explanation.
• Concentrate on understanding the logic of the module instead of concentration
entirely on the technique used.
• Work out all class examples, self-study work and laboratory work thoroughly
and completely.
• Test your increasing knowledge daily.
•
•
•
•
•
•
When answering any assessment:
Read the question carefully; make sure you know what is being asked.
Then, stop and think.
Write your answer systematically and as neat as possible.
Show all your calculations at all times, i.e. how you arrived at the solution.
Make sure that you manage your time effectively, in other words, do not spend
more time on one question than is available. Work fast and accurately!
Work through tutorials, previous test and examination papers, in order to get
used to the style and standard of the papers.

Attendance at laboratories is compulsory and students are advised to spend some time in
the laboratories for preparation and developing skills in the use of equipment and software
packages for solving well-defined problems. The laboratory weights and their due week
numbers for the module are given in section 2.2 and 2.4. Each laboratory work is important
since it forms part of the assessment of the module.

5. SAFETY COMPONENT
5.1
General Safety
Close attention should be given to all aspects of safety throughout training, and the highest
possible standards insisted upon. There is a special need to emphasize the fundamental
safety rules of behaviour, dress and practice when the trainee enters the workshop.
Instructors have a particular responsibility to set a good example and to check without
delay any departure from safe working practices by trainees. Individual responsibilities in
respect of the safety of all persons in the vicinity of the working area must be clearly
understood by everyone. It is essential to develop safe working habits.
5.1.1 What to do
•
•
•
•
•
•
Think before you act.
Ask if in any doubt.
Help to keep gangways clear.
Keep your bench and working area tidy.
Find out the position and type of fire appliances available.
Report all accidents to your supervisor
5.1.2 What not to do
•
•
•
•
•
•
•
Do not run.
Do not play practical jokes.
Do not touch any equipment or try out machines unless authorized to do so.
Do not leave rubbish lying about.
Do not walk under suspended loads.
Do not attempt to give first aid unless you are competent to do so.
Do not throw things.
5.1.3 Further points to consider
•
•
•
•
•
•
•
•
•
5.2
Wear your overalls buttoned up.
Roll up your overall sleeves above the elbows or button up the cuffs.
Keep hair short or wear a cap.
Obey all safety rules and signs.
Report any accident, however slight.
Have all injuries properly treated, however minor.
Do not wear torn overalls.
Do not wear rings or a watch when working.
Do not take chances.
Hand and Power Tools
All tools must be used in a safe manner, in particular sharp tools such as knives or
screwdrivers. These should be held in such a way as to minimize the chances of cuts to
the user if they slip from the work. The snipping of wires with side-cutters can lead to bits
of wire entering the eye and therefore goggles should be worn for such work. These tools
must be electrically safe and should be inspected regularly for cable wear and loose
16
connections. They should never be used without a guard or some form of protection fitted
and adjustments to these tools should only be made once they have been disconnected
from the supply. Soldering irons should always be kept covered to prevent accidents
leading to burning of the skin or of the flex of the soldering iron. The work being soldered
or de-soldered should be securely gripped and the work should take place on a heat-proof
mat. Excess solder should be wiped off using a wet cloth or sponge and should not be
flicked off. Care should also be taken to avoid breathing in the fumes of the flux.
5.2.1 Protective Clothing
Whether or not this is worn depends on the regulations and on the work taking place in
the workshop. Long hair should be tied back and if hair preparation is used the hair should
also be covered whenever working close to a naked flame.
