Fluid Mechanics

How liquids and gases flow, push and carry energy. Unit 1 is open now: 13 lessons, 6 simulations, quizzes and a building water-supply project.

Simulation Lab
Unit 1

Introduction To Fluid Mechanics

Each lesson follows nine steps: a real-world problem, a prediction, an experiment, the idea, the derivation, a worked numerical, real applications, a check against the simulation and a short quiz.

Unit 1 Engineering Project: A Building's Water Supply

Opens when all 13 lessons are completed. Use the simulations and calculators to size a real pump and tank system.

Coming Next

Units 2 onwards (fluid properties, pressure and its measurement, fluid kinematics and more) will open one by one.
