## MECHANICAL PRINCIPLES B

 SHE Level 1 SCQF Credit Points 10.00 ECTS Credit Points 5.00 Module Code M1H324801 Module Leader Richard Danyi School School of Computing, Engineering and Built Environment Subject Mechanical Engineering Trimester B (January start)

### Summary of Content

The aim of this module is to provide students with a foundation in the knowledge of mechanical engineering science and principles, and apply them to the design and analysis of hydrostatic, hydrodynamic and thermodynamic systems. The percentage of Work Based Learning for this module, as represented by the Independent Learning Activity Type , is 55%. There is no Work Based Assessment, but reflective learning is encouraged.

### Syllabus

The teaching syllabus will cover the following areas: Introduction to Thermofluids: Definition of a fluid. Ideal and real fluids. Perfect gases. Compressible and incompressible fluids. Dimensions and units. Distinction between a fluid and a solid. Shear stress, velocity gradient and viscosity. Newtonian and non-Newtonian fluids. Description of phase. Fluid as a liquid, gas or vapour. Fluids: Fluid statics. Pressure in static fluids. Measurement of pressure, manometry. Descriptive treatment of flow. Comparison of laminar and turbulent flow. Reynold's Number. Continuity, momentum and energy equations. Use of energy equation to analyse single pipe systems. Thermodynamics: Basic definitions of systems. The perfect gas. The equation of state for a perfect gas. The 1st law of thermodynamics. The non-flow energy equation. Application to constant volume, constant pressure, isothermal, isentropic and polytropic processes.

### Learning Outcomes

On completion of this module the student should be able to:1. demonstrate an understanding of fluids and their basic properties;2. measure and calculate fluid pressure;3. analyse flows, pressures and energies in pipe systems;4. apply the principles of work and energy in compressible fluid flow systems;5. evaluate heat, work and energy terms for closed systems using the 1st law of thermodynamics.

### Teaching / Learning Strategy

To support the student learning experience this module's lectures and seminars are carefully structured to present a consistent and logical progression of topics and concepts. The lecture delivery will be enhanced by a variety of forms including, where appropriate, computer based animations and other multimedia forms. The students will be encouraged to reflect upon the theoretical learning within the work place and the application of newly learned concepts to the work environment. Feedback will be provided to students as follows: Students will be provided with feedback within two weeks of submission of all summative assessments providing information on strengths, weaknesses and suggestions for corrective action. Student feedback on teaching, learning and assessment will be sought at the end of the semester through a module evaluation questionnaire. Work Based Education aims to maximise the direct and digitally mediated contact time with students by practicing teaching and learning strategies that use authentic work based scenarios and encourage action learning, enquiry based learning, problem based learning and peer learning. All these approaches aim to directly involve the students in the process of learning and to encourage sharing of learning between students. The module team will determine the level and accuracy of knowledge acquisition at key points in the delivery, inputting when necessary either directly or with the support of external experts who will add to the authenticity, the credibility and application of the education and learning to the workplace.
