Summary of Content

This unit is designed to provide basic concepts of thermodynamics and fluid mechanics. A general approach is used in order to provide the prior knowledge necessary to tackle more specialised engineering subject areas. The percentage of Work Based Learning for this module, as represented by the Independent Learning "Activity Type" , is 61%. Work Based Assessment is 30%.

Syllabus

The taught syllabus will cover the following areas: Introduction to Thermo-Fluids: Definition of a fluid. Ideal and real fluids. Perfect gases. Compressible and incompressible fluids. Dimensions and units. Description of phase. Distinctions between a gas, a fluid and a solid. Shear stress, velocity gradient and viscosity. Newtonian and non-Newtonian fluids. Fluids: Fluid statics. Pressure in static fluids. Measurement of pressure; manometry. Descriptive treatment of flow. Streamline and streamtube concepts. Comparison of laminar and turbulent flow. Reynold's Number. Continuity, momentum and energy equations. Evaluation of friction factor using Moody chart. Losses due to fittings, bends, etc. Use of energy equation to analyse simple pipe systems. Thermodynamics: Basic definitions of systems, heat and work. Introduction to thermodynamic properties. The First Law of Thermodynamics. The non-flow energy equation and internal energy. Use of thermodynamic tables. Interpolation. The steady flow energy equation and enthalpy. Property diagrams. Phase change and saturation lines. Introduction to the Rankine Cycle. Cycle efficiency.

Teaching / Learning Strategy

A basic lecture approach, supported by tutorial sessions, suitably-structured seminars and laboratory work. (C2) Learning and teaching strategies will be developed and implemented, appropriate to students' needs, to enable all students to participate fully in the programme. Work Based Learning that will complement this module will be agreed with each employer and be reflected in the Individual Apprentice Learning Plan for the year.

Transferrable Skills

- Students should develop their problem solving skills. (C2, C4, C5, D1, D2, D1,D4, C4, C5, E1, B1, B2) - Courseworks may include essay reports which should enhance report writing and presentation skills. (D2,D5) - Research of reference material in libraries and other sources and the analysis of this material should improve the skills related to the preparation of literature reviews. (D1,D2) - Independent learning skills should be developed. (D8) - Laboratory work should enhance teamwork skills. (D7) Mapped to SDS-GA LTOs: 1.2-1.5, 2.2, 2.3, 4.1, 5.1
