Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

EDX130B – Use technical mathematics (basic)
EAX101B -  Perform calculations related to simple fluid systems

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 Outcomes


 


Details of Learning Activities

Teacher-led lessons which will include:
*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
*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).

Student learning activities will include individual and team problem solving activities which address the designated areas of underpinning knowledge for each element. Hence, students will:
*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
*Solve problems on head loss through parallel and series pipes
*Calculate forces exerted by flowing fluids

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:

• A  mid-semester written examination.  This exam  will contribute 45% of the final overall mark.  It will cover all elements related to pumps.

• Quizzes during the semester will contribute 5% of the final overall mark.

• An end-of-semester written examination. This exam will contribute 50% of the final overall mark. It will cover head loss through pipes and forces exerted by flowing fluids.

  Information regarding dates of the assessment will be provided by the instructor.

To pass this course, it is necessary to demonstrate competency  in each element (i.e. at least basic understanding of fundamental concepts and the ability to solve the relevant problems). Very importantly, in order to pass this course the attainment of a grade of at least PASS for each element of competency is imperative.
