Answer:
Enabling environments encourage babies and young children to play because they feel relaxed, comfortable and 'at home' in them. When children feel emotionally safe and secure they are able to explore and find out about the place they are in and the things they can see, touch, manoeuvre or manipulate.
The boundary layer thickness is usually defined as the distance from the wall to the point where the flow velocity reaches 99 % of the free stream value.
In the very thin boundary layer associated with free stream flows with high Reynolds numbers, a steep rise in velocity occurs perpendicular to the wall.
Boundary layer thickness = 0.37*Distance on x-axis/(Reynolds Number^(1/5))
δ = 0.37*x/(Re^(1/5))
This formula uses 3 Variables:
Variables Used
Boundary layer thickness - (Measured in Meter) - Boundary layer thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity.
Distance on x-axis - (Measured in Meter) - Distance on x-axis is the distance of point measured along x-axis form origin.
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
