Module overview
This module continues to develop the fundamental themes on fluid mechanics introduced in the module FEEG1003 “Thermofluids” and applies them to the study of incompressible fluids in adiabatic conditions. It will focus on problems associated with water flowing in closed conduits (e.g. pipes) and open channels (e.g. rivers). The material that will be taught includes a good balance between theoretical principles (i.e. mass, momentum and energy conservation principles) and their application to real problems in hydraulic engineering. In dealing with closed conduit flows students will learn how to use these principles to find ways of delivering a required flow rate to some chosen locations under prescribed conditions. When studying open channel flows, students will learn how to predict water levels for a given channel geometry, bed condition (i.e. bed roughness and slope) and flow rate.
The module represents a pre-requisite to CENV3061, Engineering Hydrology and CENV6155 Hydraulic Engineering and Sediment Transport.

Learning and Teaching
Teaching and learning methods
The module is divided into 12 lectures devoted to pipe flows 4 lectures devoted to turbo-machinery and 20 lectures devoted to open channel flows. Lectures are interspersed with tutorials where you will be supported in learning the pipe network software EPANET, which you will be expected to use for one of the assessments of this module. Some extra tutorials will be also delivered to help you to conduct the laboratory experiments which you are also expected to carry out for another assessment of this module.
