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 centrifugal 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 Outcomes

Details of Learning Activities

You will be involved in the following learning activities to meet requirements for this course/Program
• Lectures
• Tutorials
• Projects
• Site visits
• Invited lectures

Lecturer -led Focus lessons, demonstrations and tutorials will include:
*Determination of head loss through parallel and series pipes
*Determination of forces exerted by flowing fluids (use of impulse-momentum equation, the case of pipe with changes in direction and/or cross-section is considered).
*overview of pump types
*Overview of Rotodynamic pumps. Emphasis will be laid on centrifugal pumps
* Pump selection
*Overview of cavitation (causes,effects, preventive measures)
*Calculations on a fluid circuit that includes a pump

Student learning activities will include individual and team problem solving activities which address the designated areas of underpinning knowledge for each element.
A team journal in which all information relevant to the course is recorded  (e.g., record of all material covered, class handouts, problems and solutions; team reflections) is allotted 5% of the overall mark.
A minimum of 20% of the scheduled teaching hours will be allocated to self guided learning activities.
Hence, students will:

*Solve problems on head loss through parallel and series pipes.
*Demonstrate their ability to identify different types of pumps
*Solve problems on pump selection
*Solve problems on cavitation
*Solve problems on fluid circuit that includes a pump

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 of this unit will involve completion of:
• Assignment 1, based on Element 4 20%
• Assignment 2, based  on Element 5 (15%)
• Team Journal (5%)
• Exam, 60%

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, 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.

Other Information

• Student directed hours involve completing activities such as reading online resources, project work, individual student-teacher course-related consultation. Students are required to self-study the learning materials and complete the assigned out of class activities for the scheduled non-teaching hours. The estimated time is 20 hours outside the class time.

Late submission:

If you require an extension for 7 calendar days or less (from the original due date) you must complete and lodge an Application for Extension of Submittable Work (7 Calendar Days or less) form and lodge it with the Senior Educator/ Program Manager.
The application must be lodged no later than one working day before the official due date. You will be notified within no more than 2 working days of the date of lodgement as to whether the extension has been granted.

If you require an extension of more than 7 calendar days (from the original due date) you must lodge an Application for Special Consideration form under the provisions of the Special Consideration Policy, preferably prior to, but no later than 2 working days after the official due date.

Assignments submitted late without approval of an extension will not be accepted nor marked.
