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

• 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

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.
