Course Description

This unit covers the skills and knowledge required to perform calculations for complex systems including pump selection, head losses (more advanced) and determination of fluid dynamic forces.

National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:	EAX061B Perform calulations related to more complex fluid systems
Element:	1. Select a pump using pump performance curves for a given discharge and pressure head.
Performance Criteria:	1.1 A ‘family tree’ of pump types can be drawn.  1.2 The principle of operation of rotodynamic pumps, particularly  centrifigul types is understood and used to inform decisions  involving fluid systems.  1.3 Two or three pumps can be pre-selected using the duty point in  conjunction with a manufacturer’s catalogue.  1.4 Flow, head, power and efficiency are determined at the duty point  on the performance curve for each pump.  1.5 The pumping cost in $/ML is determined for the duty point.
Element:	2. Consider the causes and effects of cavitation.
Performance Criteria:	2.1 The causes and effects of cavitation is understood and used to  inform decisions involving fluid systems.  2.2 NPSHA is determined at the duty point and compared to NPSHR  to establish whether cavitation will occur.  2.3 Modifications to the inlet system can be designed which will  reduce the likelihood of cavitation.  2.4 The influence of fluid temperature and pressure on the likelihood  of cavitation is understood and used to inform decisions involving  fluid systems.
Element:	3. Perform calculations on a fluid circuit that includes a pump or turbine.
Performance Criteria:	3.1 The equations of fluid power are used to calculate the fluid power and efficiency involved with fluid flow in a pump or turbine.  3.2 The modified Bernoulli Equation is used to calculate property changes to a flowing liquid with a pump or turbine in the fluid  circuit with or without a head loss term.  3.3 The pump head and system head curves are superimposed to find the optimum duty point.
Element:	4. Determine head loss through pipe networks.
Performance Criteria:	4 .1 The difference in head loss for parallel pipes vs series pipes is  understood and used to inform decisions involving fluid systems..  4.2 The head loss is calculated through parallel and series pipes.  4.3 A simple network of pipes and fittings is reduced to an equivalent  single pipe.  4.4 Head loss and flow rate through the equivalent system is  calculated.  4.5 Methods of analysis for more complex networks is understood  and used to inform decisions involving fluid systems.
Element:	5. Calculate the forces exerted by flowing fluids.
Performance Criteria:	5.1 The impulse-momentum equation is used to calculate the force  developed by a fluid jet striking a stationary plate that may be  perpendicular, inclined or curved.  5.2 The force, torque and power developed when a fluid jet strikes a  series of moving blades are calculated.  5.3 The forces developed by a fluid flowing in a duct or pipe with  changes in direction and/or cross-section are calculated.

Learning Resources

Prescribed Texts

References

Other Resources

Weekly notes will be posted on the blackboard. Handouts are distributed during class on a need basis. Handouts distributed during class are not posted on the blackboard.

 Students will be able to access information and learning materials through myRMIT and may be provided with additional materials in class. List of relevant reference books, resources in the library and accessible Internet sites will be provided where possible. During the course, you will be directed to websites to enhance your knowledge and understanding of difficult concepts.

 

Overview of Assessment

Assessment are conducted in both theoretical and practical aspects of the course according to the performance criteria set out in the National Training Package. Students are required to undertake summative assessments that bring together knowledge and skills. To successfully complete this course you will be required to demonstrate competency in each assessment tasks detailed under the Assessment Task Section.

Your assessment for this course will be marked using the following table:

NYC (<50%) Not Yet Competent

CAG (50-59%) Competent - Pass

CC (60-69%) Competent - Credit

CDI (70-79%) Competent - Distinction

CHD (80-100%) Competent - High Distinction

Assessment Tasks

Assessment of this unit will involve completion of: 

Assessment 1:  Assignment 1, based on Element 4

Weighting towards final grade (%): 20% 

Assessment 2:  Assignment 2, based  on Element 5 

Weighting towards final grade (%): 20%

Assessment 3:  Team Journal

Weighting towards final grade (%): 10%

Assessment 4:  Exam

Weighting towards final grade (%): 50% 
 
In order to achieve competency in this course, students will need to demonstrate competency in each element (i.e. students will need to demonstrate at least basic understanding of fundamental concepts and the ability to solve the relevant problems). The exam is closed book. Formula sheet is provided by the instructor. Only scientific calculators are allowed. No aide memoire (i.e. cheat sheet) is permitted.
A record of student class activities, team reflection, class handouts, material posted on the blackboard, etc, is to be kept in the Team Journal. To ensure that the competency standards are being met, throughout the semester, student progress will be closely monitored.
