18. Laminar and turbulent flow (Cond.)

The chapter discusses the fundamentals of laminar and turbulent flow in hydraulic engineering, detailing the characteristics, governing equations, and practical implications of each flow condition. Key problems are solved to illustrate the application of related concepts, such as maximum velocity, pressure drop, shear stress, and terminal velocity of particles in fluid. Moreover, it introduces Reynolds decomposition to describe turbulent flow, emphasizing the transition between laminar and turbulent regimes.
