Learning Outcomes
Having successfully completed this module you will be able to:
- B1 Thermofluids requires the application of knowledge of mathematics, and engineering principles to broadly-defined problems such as types of fluid flow, statics, thermodynamic process and multi-process systems such as heat engines. This occurs in both formative and summative types of assessment. B10 A lecture and linked tutorial class discussion directs students to apply a holistic and proportionate approach to the mitigation of security risks associated with general electrical power generation and again specifically for nuclear fission. B12 FEEG1003 gives students practical laboratory and workshop skills to investigate broadly-defined problems with 4 practical labs addressing: 1. Properties of ideal gases, 2. Linear heat engine, 3. Conservation of mechanical energy, 4. conservation of momentum. all 4 labs are formatively assessed. B16 Students function effectively as an individual in formative tutorial class assessment and in general where individual work is required i.e. tutorial and exam assessments. Students work as a member or leader of a team during the practical laboratory classes where the take responsibility for different aspects of the experiments. B2 In the FEEG1050 summative assessment students solve a substantial engineering problem including a problem-solving element requiting mathematical and engineering principles and are also asked to comment on answers, expand of applications etc. B8 A lecture and linked tutorial class discussion directs students to identify and analyse ethical concerns associated with imported gas supplies (with regards to the Russian invasion of Ukraine) and for using nuclear fission for electricity generation . B9 A lecture and linked tutorial class discussion directs students to identify and analyse risks associated with different from of electricity generation and imported energy. C1 Later summative and formative assessments require the application of knowledge of mathematics, and engineering principles to the solution of complex problems.
