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: Social globalisation refers to the sharing of ideas and information between and through different countries. In today's world, the Internet and social media is at the heart of this. Good examples of social globalisation could include internationally popular films, books and TV series.
Explanation:
In the irreversible tide of globalization, whether developed countries or developing countries, regardless of whether it is willing, have consciously or unconsciously integrated into the process, or they will lose living space. Certain culture is linked to a certain level of economic development. Economic globalization is bound to have profound effects on global culture, so all kinds of culture are undergoing great changes under the great driving force of economic globalization. Culture has a lot to with the contemporary way of life, so globalization has a great impact on the consumers (David, 1996). In the process of globalization, many enterprises embark on a path from Localization to globalization, and McDonald’s is just the example that plays an important part in the fast-food business in the world. McDonald’s has made a great success in the international arena since its inception, and it has left a deep impression on the mind of many consumers. Now McDonald’s is not just a restaurant, but also a cultural symbol, which has an impact on consumers. McDonald’s has implemented a series of marketing strategies in order to adapt to the cultural environment of other countries, and this changes also affect the local consumers. Now McDonald’s has become a global icon, and it affects the lifestyle of people worldwide. Globalization in the culinary domain is the export of a food and its specialities towards foreign countries. More particularly, in the field of the fast food it is necessary to notice the major origin of this export: the United States. In the post Second World War Era, the United States has exported its culture massively, in particular its culinary culture. So the first one McDonald’s outside the United States opened in 1967 in Canada, before arriving in 1971 in Europe (the Netherlands). Since then, the burger has continued to see growth in popularity.

The correct answer is that defines a risk society is the
first choice in which it reads as the central issue is risk and how to minimize
or prevent it.
It is because a risk society means that the society’s issue
is the risk that the society is involved with and in order to prevent these
risks from happening, the society should engage of doing things to prevent it
from ever occurring.
