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
This unit of competency sets out the knowledge and skills required to apply fluid mechanic principles in mechanical engineering. This includes the principles and applications of fluids, fluid components, fluid status, fluid flow, fluid power, and forces developed by flow in fluids. To perform calculations to determine changes, forces etc, fluid flow, head loss in pipes and through open channels, to determine operational aspects of a pump in a system and to describe the basic types of fluid machinery.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. However, practice in this unit is subject to regulations directly related to occupational health and safety and where applicable contracts of training such as apprenticeships and traineeships.

Overview of Assessment
Assessment may incorporate a variety of methods including written/oral activities and demonstration of practical skills to the relevant industry standards. Participants are advised that they are likely to be asked to personally demonstrate their assessment activities to their teacher/assessor.
Feeback will be provided throughout the course
Evidence can be gathered through a variety of ways including:
observation of processes and procedures;
oral and/or written questioning on required knowledge and skills;
testimony from supervisors, colleagues, clients and/or other appropriate
inspection of the final product or outcome;
a portfolio of documentary evidence.
Graded Assessment out of 100 Marks will be based on the results obtained for Assignments/Practical reports/Unit tests/Exams.
Students must gain pass in all forms of assessment in order to pass the competency.
Assessment for this course is throughout the course delivering and exam period. Your knowledge and understanding of the course content is assessed through completion of four assessment tasks. All the assessment tasks allow you to apply the required knowledge and skills in relation to interpret fluid mechanics manuals and specifications.
The assessment for this subject will consist of:
Assessment 1 Part Exam Fluid Mechanics Principles 40%
Assesment 2 Final Exam Fluid Mechanics Principles 40%
Assessment 3 Laboratory work and/or Assignment 20%
Note: The marks of the assignments towards the final marks of the subject would be considered only if the knowledge displayed in the assignments is reflected in the written tests. The practical will be graded as pass or fail.
