Pre-Requisite Knowledge

Satisfactory completion of year 1 modules for BEng Building Services Engineering or equivalent.

Summary of Content

The module covers the design and analysis procedures for water supply, waste-water disposal, general fluid flow systems including turbo-machinery, refrigeration and heat pumps. Also the application of dimensional analysis to fluid flow systemsis dealt with, making particular reference to experimental investigations and model studies.

Syllabus

The taught syllabus will cover the following areas: Water Supply and Disposal: Sources from which water is obtained for supply purposes. Assessment of water quality by analysis. Processes required for the treatment of water. Design of supply systems. Design of waste water drainage systems. Processes required for waste water treatment and disposal. Pipe and Duct Sizing: Fluid flow in pipes with pumping and fan operated duct systems. Effects of boundary layer formation. Energy losses in systems. Determination of friction factors. Design of ventilating systems and cold and hot water systems. Sizing of pipes and ducts and energy loss calculations. Flow measurement: Applications of pitot tubes, orifices, venturi-meters, notches and anemometers. Introduction to advanced flow measurement techniques. Analysis of systems using standard instruments. Turbo-machinery: Types and performance characteristics of fans. Comparison of different designs of fans and pumps. Matching of pumps and fans to system requirements. Effect of speed changes. Use of dampers and inlet guide vanes. Dimensional Analysis: Fundamental dimensions for fluid mechanics and thermodynamics. Derivation of general expressions in terms of dimensionless groups for flow systems. Identification of important non-dimensional numbers. Derivation of shape parameters for rotodynamic machines. Speed relationships. Model Studies using techniques of dynamical similarity. Refrigeration: Vapour compression and vapour absorption refrigeration and heat pump cycles. Condenser undercooling, compression efficiency and volumetric efficiency. Refrigerants.

Learning Outcomes

The Engineering Benchmarks A2,A7,B1,B2,B3,B5,B7 and C2 as specified in the BEng Building Services Engineering Specification Document apply to this module.The student should be able to:- Explain the units used and the processes involved in the treatment of water and waste-water (A2)- Apply design procedures to and analyse water supply systems and waste-water disposal systems (B1,B2)- Analyse and design duct systems for air flow including fans (B1,B3)- Analyse and design pipe networks for cold and hot water systems including pumps (B1,B3)- Explain the applications of standard flow measuring instruments and determine fluid flow rates using the appropriate formulae (A2,C2)- Explain the performance characteristics of different types of turbomachinery (A2)- Apply design procedures to pumps and fans and to the systems in which they operate (B5)-Derive mathematical expressions for fluid flow systems by using dimensional analysis and apply the concept of dynamical similarity to fluid flow systems including model investigations (A2)

Teaching / Learning Strategy

The module will put considerable emphasis on a sound understanding of fundamental fluid concepts and principles in order to develop the ability to design and analyse complex fluid systems. This approach will be reinforced by appropriate seminars/tutorials/laboratories where empirical techniques will be viewed critically. The environmental protection theme will be encouraged throughout the module. Learning and teaching strategies will be developed and implemented, appropriate to students' needs, to enable all students to participate fully in the programme.
