Aims

| |

1 |
Contribution of the course to the program objectives (N°) AA1.1, AA1.2, AA1.3, AA2.1, AA2.2, AA4.1, AA4.2, AA4.4, AA5.3 Specific learning outcomes of the course : - Design of reservoir and tanks under hydrostatic pressure load
- Design of pressurized pipes and water distribution networks
- Design of simple orifices and weirs
The evaluation of the course includes an oral assignment, which leads the students to develop his ability to synthetize his knowledges in order to write on the blackboard and present orally a clear and concise answer to a question on the course. |

Content

1. Introduction. Hydraulics in Civil Engineering. Properties of liquids. Pressure.

2. Hydrostatics

- Differential equations and integrals, manometers, resulting pressure forces
- Theory of floats

- Fundamental equations, Lagrangian and Eulerian approaches
- Displacements, deformation and rotations

- Perfect fluid

- Dynamics: Euler equation, integral equations of Lagrange and Bernoulli

- Laminar flow

- Steady laminar flow in pipes: parabolic velocity profile and discharge integral (Poiseuille)

- Turbulent flow

- Headlosses : eddy losses (Darcy, Moody-Nikuradse) and minor losses

5. Applications

- Liquid-sold interactions, hydrodynamic forces
- Orifices and weirs
- Pressurized flow in pipes and water distribution networks (steady flow)

- Branched networks

- Meshed networks (Hardy-Cross) and nodal methods (Newton- Raphson)

Teaching methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

The activities are organised as follows:- Lectures for the main theoretical topics
- Practical exercises on the different chapters; laboratory work (floats and pipes); small project work on the calculation of a water distribution network

Evaluation methods

Due to the COVID-19 crisis, the information in this section is particularly likely to change.

Continuous evaluation based on laboratories, projects and a written test about the exercises.Oral exam for the theoretical part.

Online resources

Moodle website where different resources are made available : PowerPoint slides used for the lectures, videos, partial lecture notes, exercises with solutions, other useful documents (practical information about the exercises, schedule of the activities, ...)
