How do you find the boundary layer thickness of a pipe?

Social Studies
1 answer:
QveST [7]1 year ago
3 0

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.

explain how economic problems, perestroika, and glasnost contributed to the fall of the Soviet Union.
tankabanditka [31]
Glasnost led to revolutions in Soviet states, while perestroika created economic confusion. Glasnost resulted in the imprisonment of military leaders, while perestroika resulted in political freedom. Glasnost led to revolutions in Soviet states, while perestroika created economic confusion. Perestroika lasted from 1985 until 1991, and is sometimes argued to be a significant cause of the collapse of the Eastern Bloc and the dissolution of the Soviet Union. This marked the end of the Cold War.

Guys give me your perspectives about smoking?<br><br> plz give valid answer otherwise dont answer
Alecsey [184]

Answer: Smoking is an action that can be viewed from various perspectives.

Explanation:

Smoking has been present in society for a long period. You can appreciate the role that this action has played and what it can play to a certain extent. From a social perspective, smoking is a social disease. People who smoke are usually in a group where they share this interest and although they may be aware of the damage that smoking can cause, this does not mean that they will quit smoking for some time.

Smoking not only hurts the person who smokes but also the one who is nearby, where one is called active smoking and a passive smoker. The passive smoker is equally likely to develop diseases caused by smoking if he is close to smokers, and it seems that many of these do not know it and only see it from the point where it only hurts the active smoker.

One of the causes for which people do not quit smoking although they know that it can harm is due to the little credibility they have. They are aware that it hurts, but not to the point that they can leave it. The addiction is also involved. People who have tried smoking have developed withdrawal symptoms, where their body exhibits symptoms of anxiety about not having what satisfies them.

In this regard, it is not a matter of judging the person who smokes but who is aware of the serious damage it can cause to health. It has been found in various scientific studies as people who smoke are more likely to develop diseases such as cancer and other problems that can affect health.

From another point of view, people can see smoking as a normal activity as well as having a drink or exercising, it is something that the person performs to seek well-being, but smoking can have greater consequences than those mentioned above.

Looking at it from a psychological point of view, smoking can be a way of dealing with the situations of daily life. Some people exercise, others meditate and others resort to smoking to relax and get ahead with the situations they are dealing with. While it is true that it is not good to judge others for the things they do, people must take responsibility and understand the consequences that each action can bring.
