Task 1 :

You have been asked to investigate fluid flows and internal fluid flow measuring instruments and associated piped systems and how they can be applied in mechanical systems.

To do this:

You will carry out practical activities safely, in accordance with relevant risk assessments. You need to produce a report that includes detail of the investigations carried out, including comparisons between measured values and those predicted by theory.

You need to use the available apparatus, to carry out practical investigations and record the results systematically for flow through a piped system including a tapered pipe using appropriate instruments to measure pressure and flow rate. You will need to include two measuring systems, including Venturi apparatus/meter.

You should then:

Outline in your report the relevant theory for each investigation and compare your measured results with those predicted by theory. You should consider pressure and fluid flow parameters, and changes in behaviour of water as it passes through a Venturi meter.

A portfolio of results gathered by experimentation when investigating fluid flows and internal fluid flow measuring instruments and associated piped systems and by theoretical calculation, supported by

• images,
• observation records
• mathematical modelling
• calculations
• evaluations and

conclusions

29/B.D2	Evaluate the behaviour and parameters of at least one tapered pipe and at least two measuring instrument fluid systems, comparing the results from safely and accurately conducted experiments against theoretical calculations.
29/B.M3	Conduct experiments safely and accurately to determine the behaviour and parameters of at least one tapered pipe and at least two measurement instrument fluid systems.
29/B.M4	Analyse, using the results and theoretical calculations, the behaviour and parameters of fluids in at least one tapered pipe and at least two measuring instrument fluid systems.
29/B.P3	Conduct experiments safely to determine the behaviour and parameters of at least one tapered pipe fluid system.
29/B.P4	Conduct experiments safely to determine the behaviour and parameters of two measurement instrument fluid systems.
29/B.P5	Explain, using the results and theoretical calculations, the behaviour and parameters of fluids in at least one tapered pipe and at least two measurement instrument fluid systems.

Notes to Assessor and technician

Task Learners should work together in small groups to carry out the practical investigations, but each learner should produce their own portfolio of results and analysis. The investigations should be carried out simply using fluid flow measurement apparatus sufficient to cover the content, for example Bernoulli equipment with water tank and control valves, Venturi meter, orifice meter, velocity meter, turbine meter, closed section wind tunnel with manometer and other fluid flow measurement instrumentation.
