Hello! Originally, the media was intended to be a watchdog for the citizens when the 1st Amendment came out (allowing freedom of press), and they continue to be. They go behind the scenes, and inform the public on everything to ensure the government isn't keeping any bad secrets from the citizens, and that they aren't taking too much power from the people. Also, the media helps itself by understanding they have the right to publish unrestrained media. In some countries, however, the media is controlled by the government. Hope this helps! :)
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.

The Second World War was history's largest and most significant armed conflict. It served as the breeding ground for the modern structure of security and intelligence, and for the postwar balance of power that formed the framework for the Cold War. Weapons, materiel, and actual combat, though vital to the Allies' victory over the Axis, did not alone win the war. To a great extent, victory was forged in the work of British and American intelligence services, who ultimately overcame their foes' efforts. Underlying the war of guns and planes was a war of ideas, images, words, and impressions—intangible artifacts of civilization that yielded enormous tangible impact for the peoples of Europe, east Asia, and other regions of the world.
