Overview of assessment 

A person who demonstrates competency in this unit must be able to evaluate hydrodynamic systems, including evaluation of system performance, selection of components and calculation of fluid force.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors must be satisfied that the candidate can competently and consistently:

• determine parameters and context of evaluation task
• determine WHS, regulatory requirements, risk management and organisational procedures
• identify features, functions and components of a range of hydrodynamic systems
• investigate and review sustainability implications, features and functions of hydrodynamic systems and components
• apply correct hydrodynamic principles and techniques for particular hydrodynamic systems
• evaluate components and systems to determine safety, efficiency and fitness for purpose
• report and document results.

Context of and specific resources for assessment 

• This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
• Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
• Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment 

• Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
• Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
• Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure correct interpretation and application.
• Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
• Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
• Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment 

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Hydrodynamic systems 

Hydrodynamic systems include:

• fluid vessels (e.g. static dams, tanks and pools, and vessel in dynamic applications)
• pumping systems (e.g. industrial wash, fire prevention and irrigation)
• turbines for hydro-electric power generation
• components, such as fluid containers, ducts, pipes, valves, pumps, turbines and fluid measuring devices
• open channels for liquid transfer

Sustainability 

Sustainability is used to mean the entire sustainable performance of the organisation/plant, including:

• meeting all regulatory requirements
• conforming to all industry covenants, protocols and best practice guides
• minimising ecological and environmental footprint of process, plant and product
• maximising economic benefit of process plant and product to the organisation and the community
• minimising the negative WHS impact on employees, community and customer

Appropriate licensed technical and professional assistance 

Appropriate technical and professional assistance may include:

• technical support and advice relating to elements which have intrinsic dangers, such as:

• high pressure
• energised fluid vessels
• high temperatures and heat energy capacity
• wiring with high current control voltages above extra low voltage

• professional support for technologies, such as:

• specialist electric motor drives and controllers
• specialist materials, plastics, metal alloys and nano materials
• special processes, foundry, alloy welding, heat treatment, sealing and fastening

WHS, regulatory requirements and enterprise procedures 

WHS, regulatory requirements and enterprise procedures may include:

• WHS Acts and regulations
• relevant standards
• codes of practice from Australian and overseas engineering and technical associations and societies
• risk assessments
• registration requirements
• safe work practices
• state and territory regulatory requirements applying to electrical work
