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.

<span>Upper
class women were often depicted as more inferior to men than the lower class
women because of the limitations of the things that upper class women can
do. Upper class women considered their
status and often just stays at home, learning essential skills for an upper
class woman, while lower class women were able to do difficult labor than upper
class women.</span>
<span>Context
wise, lower class women tend to have more knowledge and tend to learn and
explore more things and skills due to the fact that they were never assigned a
limitation to the things that they are doing.
They are often having difficult jobs on where they can learn from.</span>
<span>The answer would be D) Europeans wanted new sources of raw materials and new markets to which they could sell goods, increasing European wealth.
Why is it D)? because </span>Europeans were also interested in the other reasons, but only after they began exploring ways to make money.
The medulla oblongata on the base of our brain
Answer:
It extended from East Asia to the Black Sea in Eastern Europe.
Explanation:
The Mongol Empire had its origin in the Mongolian steppe, when Genghis Khan united the nomadic tribes of Mongolia under the same banner.
From there, it spread to China, Central Asia, Persia, The Middle East (where the Mongol army destroyed Baghdad, perhaps the most important city of the world at the time), Russia, and Eastern Europe.
The Mongol Army advance was only stopped as west as Hungary.
In conclusion, we can see that the Mongol Empire stretched from East Asia to the Black Sea.
