Webb9.2.2 Turbulent flow. The laminar boundary layer over a smooth flat plate is known to become unstable to small disturbances at a sufficiently high Reynolds number, typically in the range of 1.5 × 10 5 < Re x < 1.5 × 10 6. In this range the laminar flow develops periodic and then fully random turbulent fluctuations in the flow. WebbEach layer of the layered architecture pattern has a specific role and responsibility within the application. For example, a presentation layer would be responsible for handling all user interface and browser communication logic, whereas a business layer would be responsible for executing specific business rules associated with the request.
