Fluid Mechanics: Pipe Flow, Head Loss, and the Moody Diagram

Understanding how fluids behave inside pipes and conduits is essential for designing efficient water supply systems, industrial pipelines, and environmental infrastructure. This text-only course guides you through the fundamental principles of fluid mechanics, focusing on pipe flow dynamics and frictional losses. You will gain the confidence to analyze fluid systems and solve engineering calculations systematically. What you'll learn: - Understand the fundamental principles of laminar and turbulent flow in circular pipes - Calculate frictional head loss using the Darcy-Weisbach and Hazen-Williams equations - Navigate the Moody diagram to determine friction factors for various flow regimes - Analyze minor losses in pipe fittings, valves, and transitions - Apply modern numerical approximation methods to solve the Colebrook-White equation - Evaluate fluid flow behavior in non-circular conduits and basic piping networks The course starts with foundational definitions of fluid properties, viscosity, and flow regimes before moving into practical head loss calculations. You will progress from manual calculations using charts to modern, systematic approaches for analyzing complex fluid systems. This course is designed for engineering students, junior designers, and professionals looking for a clear, written refresher on pipe hydraulics. No advanced fluid dynamics experience is required, as we build your understanding from the ground up. Start reading today to master the core mechanics of fluid transport systems.
