### Pre-Requisite Knowledge

Programme entry requirements or equivalent

### 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.

### 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. The reversible, adiabatic process and the practical significance of entropy. Behaviour of perfect gases. The equation of state for a perfect gas. Universal and specific gas constants.

### Learning Outcomes

The Engineering Benchmarks A1,A2,B1,B2,B5,B7,C1 and C2 as specified in BSc Programme Specification Document apply to this module.On successful completion of this module the student should be able to:- 1 Define a fluid and its basic properties (A1,A2)2 Understand the principles of simple manometry (A1,A2)3 Understand the significance of Reynold's Number to laminar and turbulent flow and evaluate friction factor using the Moody chart (A1,A2)4 Analyse flows, pressures and energies for single pipe systems using the continuity and steady flow energy equations (B2,B5,C1)5 Evaluate the force on a bend/nozzle due to momentum change (B2,B5,C1)6 Understand the First Law of Thermodynamics and evaluate heat, work and/or internal energy changes for processes involving closed systems (A2,B2,C1)7 Use the steady flow energy equation for solving open system problems (B1,B2,B5,C1)8 Identify property values using steam tables and understand relevant terms such as saturated liquid, saturated vapour, dryness fraction and superheat (A2,B1)9 Calculate the efficiency of a simple Rankine cycle (B1,B5,C1)10 Use the equation of state for perfect gases to calculate property values (B1,B5,C1)

### 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.

### Transferrable Skills

The Engineering Benchmarks D1,D2,D3,D5,D6,D7 and D8 for transferable skills as specified in the BSc Building Services Engineering Programme Specification Document apply to this module. - Students should develop their problem solving skills. (D1,D3,D6) - 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)
