A boundary layer is a thin region adjacent to a surface where the effects of viscosity are significant, leading to velocity gradients in fluid flow. It develops due to the interaction between the fluid and the surface, causing the fluid's velocity to decrease from its free-stream value to zero at the surface due to friction. Factors such as surface roughness, flow speed, and fluid properties influence the thickness and behavior of the boundary layer. This phenomenon is crucial in various fields, including aerodynamics and hydrodynamics, as it affects drag and heat transfer.

What causes a boundary layer to develop in fluids?
A boundary layer develops in fluids due to the friction between the fluid and a solid surface. This friction slows down the fluid velocity near the surface, leading to the formation of a boundary layer where the flow transitions from the no-slip condition at the surface to a freer-flowing condition away from it.
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is?
The ratio of thermal boundary layer thickness to the concentration boundary layer thickness is typically denoted as Prandtl Schmidt number (PrSc). It is defined as the ratio of thermal diffusivity to mass diffusivity of a fluid and represents the relative thicknesses of the thermal and concentration boundary layers in a flow field.
Which cell layer do lateral roots develop?
Lateral roots develop from the pericycle, which is a layer of plant cells located in the outermost layer of the vascular cylinder in the root.
What type of boundary causes faulting?
A transform plate boundary, also known as a strike-slip boundary, causes faulting. This boundary occurs when two tectonic plates slide horizontally past each other, causing rocks to break along fault lines.
What causes the dipletion of ozone layer?
Chlorofluorocarbons
What is a boundary layer and what causes it to develop?
A boundary layer is a thin layer of fluid near a surface where the flow of the fluid is significantly affected by the presence of the surface. It develops due to the friction between the fluid and the surface, which slows down the flow of the fluid near the surface.

Which non-dimensional number relates the thermal boundary layer and hydrodynamic boundary layer?
prandlt no.
A convergent boundary causes what stress type?

can boundary layer take place for ideal fluids?
Yes, a boundary layer can take place for ideal fluids. A boundary layer is the separation that is associated with strong flow deceleration or strong adverse pressure gradients.
