Fluid Mechanics - Course Description

Fluid Mechanics is a fundamental branch of physics and engineering that studies the behavior of fluids (liquids and gases) at rest and in motion. This course introduces the fundamental principles governing fluid properties, hydrostatics, fluid statics, and fluid dynamics. It covers pressure distribution in fluids, hydrostatic forces on submerged surfaces, buoyancy, fluid flow descriptions, the continuity equation, Bernoulli’s equation, and the fundamental laws of fluid motion.

Through theoretical lectures and tutorial sessions, students will develop the ability to analyze fluid systems, solve engineering problems, and apply the principles of fluid mechanics to civil engineering and hydraulic applications.

Fluid Mechanics (Mécanique des fluides) - Semester 3
Welcome to the Fluid Mechanics course! This course is designed for preparatory class students (Civil Engineering / Public Works) at the ENSTP. It covers the fundamental concepts of fluids at rest and in motion, with a strong emphasis on engineering applications in civil engineering and hydraulic structures.
Course structure (45 hours) :
  • Chapter 1 - Fluid Statics : fluid properties, pressure, hydrostatic forces on plane and curved surfaces, Archimedes' principle and buoyancy
  • Chapter 2 - Fluid Kinematics : Lagrangian and Eulerian descriptions, flow classification, continuity equation
  • Chapter 3 - Dynamics of Ideal Fluids : Euler's equation, Bernoulli's theorem, Venturi meter, Pitot tube, momentum equation
  • Chapter 4 - Dynamics of Real Fluids : viscosity, Reynolds number, head losses, Moody diagram, cavitation
For each unit you will find : lecture slides, detailed course notes with worked examples, tutorial exercises (TD), online quizzes, and additional resources.
Assessment : continuous assessment based on the course grade (attendance 30%, online quizzes 20%, written exam 50%) and the TD grade (written test 60%, participation/homework 40%).
