Answer 1

Turbulent flow and laminar flow are two types of fluid flow.
Laminar flow is characterized by smooth, regular movement of fluid, while turbulent flow is characterized by chaotic, irregular movement.
Boundary Layer in Turbulent Flow and Laminar Flow Boundary layer is a layer of fluid that is in contact with a solid surface.
The characteristics of this layer are affected by the type of fluid flow. In laminar flow, the boundary layer is thin and smooth.
In turbulent flow, the boundary layer is thicker and chaotic.
Comparison of Boundary Layer in Turbulent Flow and Laminar Flow In turbulent flow, the boundary layer is thicker compared to laminar flow.
This is because the chaotic movement of fluid in turbulent flow creates more friction between the fluid and the solid surface, resulting in a thicker boundary layer.
On the other hand, in laminar flow, the smooth movement of fluid creates less friction, resulting in a thinner boundary layer.
