17. Laminar and Turbulent Flow (Contnd.)
The chapter explores the principles of laminar flow in pipes and between parallel plates, detailing the calculations needed to analyze flow characteristics such as pressure difference, velocity profiles, and shear stresses. It includes worked examples to demonstrate the application of theoretical concepts, and emphasizes practical exercises to solidify understanding of fluid dynamics in engineering contexts.

What we have learnt
- Laminar flow has a characterized low Reynolds number, typically below 2000, which means the flow is smooth and orderly.
- The pressure difference in laminar flow can be calculated using the equation derived from the principles of fluid mechanics, taking into account viscosity, density, and dimensions of the flow area.
- Shear stress at the plates can be determined from the velocity gradient and viscosity, which is crucial for designing systems that involve fluid movement.
Key Concepts
- -- Reynolds Number
- A dimensionless number that helps predict flow patterns in different fluid flow situations. Low Reynolds numbers (under 2000) indicate laminar flow.
- -- Laminar Flow
- A type of fluid flow where the fluid moves in parallel layers, with no disruption between the layers, characterized by smooth and orderly motion.
- -- Shear Stress
- The force per area exerted by a fluid on a surface, proportional to the velocity gradient of the fluid.
