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.

Answer:
Migrate from one region to another
Explanation:
Famine -food scarcity-, warfare -war situations-, and religious persecution have most often influenced people’s decisions to <u>migrate from one region to another.</u>
For centuries, <em>people have migrated from one region to another to escape from tough situations like food scarcity, war, racism, lack of opportunities, religious persecution</em>, amongst many others.
Migration can permit an individual or group of individuals (family) to have access to better opportunities and live a better-quality life.
