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.

I think so yes why wouldnt there be
The correct answer is A. rainforests are responsible for most global oxygen turnover.
This is not true because rainforests, even though they have a lot of trees, are very humid, and actually take up a lot of oxygen to be able to 'feed' the vegetation found there. Other forests actually provide most oxygen in the world, but not rainforests. The other options are correct.
People often enjoy life. The stage in the family life cycle are Charlie and Nancy enjoying is Full nest three.
<h3>What is a family life cycle about? </h3>
The emotional and intellectual stages a person have to pass through from childhood to one's retirement as a member of a family is known to be the family life cycle.
The three sub-stages of 'full nesters' are often used by marketers in terms of targeting their products to the family. They are:
- Full Nest 1
- Full Nest 2
- Full nest 3
