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.

Pre-requisite requirements - FEEG1003 and MATH1054.

Aims and learning outcomes

Aim

Having successfully completed this module, you will be able to:

  • Offer you individual and group projects to stimulate individual innovation, self-assessment and teamwork skills required in engineering.
  • Provide you with an understanding of the main theoretical principles underpinning the behaviour of water flow in rivers/channels and pipes.
  • To put you in a position to apply theoretical principles to solve problems that you will encounter when working in industry.

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

  • Mass, momentum and energy principles governing pipe and open channel flows
  • Different type of flows (i.e. uniform-non uniform, steady-uinsteady, gradually varied-rapidly varied)
  • Working principles of pumps commonly used in hydraulic engineering

Subject Specific Intellectual

Having successfully completed this module, you will be able to:

  • Analyse simple and complex pipeline systems, including pipe networks
  • Determine the capacity of pipelines, establish the pressures and the energy gradients along the pipe
  • Analyse and predict the behaviour of sub-critical and supercritical open channel flows
  • Identify and interpret situations in hydraulics in a way that is relevant to design
  • Devise solutions for problems involving open channel and pipe flows

Transferable and Generic

Having successfully completed this module, you will be able to:

  • Problem analysis and problem solving
  • Group work/team work
  • Report writing

Subject Specific Practical

Having successfully completed this module, you will be able to:

  • Operate systems used in a hydraulics laboratory
  • Exercise technical judgement and make decisions
  • Carry out and present engineering calculations

Graduate Attributes

Graduate Attributes are the personal qualities, skills and understandings that University of Southampton students have the opportunity to develop. They include but extend beyond subject-specific knowledge of an academic discipline and its technical proficiencies. The Graduate Attributes are achieved through the successful attainment of the learning outcomes of the programmes, and successful engagement with the University’s co-curriculum e.g. the Graduate Passport.

A checklist for embedding the graduate attributes is available at: https://sharepoint.soton.ac.uk/sites/ese/quality_handbook/Handbook/Employability%20Statement.aspx

Summary of syllabus content

OPEN CHANNEL HYDRAULICS

Uniform flow, the Chézy and Manning equations

Applying these equations to determine the discharge in a channel or the sizing of a channel for a particular discharge

Design guidelines including the concept of the best hydraulic section

Non-Uniform Flow including Specific Energy and Critical Depth

Understanding the possible types of flow, Sub-critical and super-critical as well as Critical, Mild and Steep slopes

Flow measurement, Weirs and Flumes

Transitions through Critical Depth, Control Points

The Hydraulic Jump

The Equation of Gradually Varied Flow

Flow Profiles

Profile Evaluation, the Direct Step Method and the Standard Step Method

 

PIPE FLOW

Equations for pipe discharge: the Darcy-Weisbach and the Colebrook-White equations.

Solving the Colebrook-White equation

Minor head losses

Pipes in Series and in Parallel

Pipe Networks, the Hardy-Cross solution

Unsteady flows in pipes: the water hammer

 

TURBOMACHINERY

Overview of Turbines

Rotodynamic Pumps, Characteristics

Understanding how the head developed by a pump is used and dissipated

Matching the Pump and the Pipeline

Summary of 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.
