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.

Based on this map, which statement is about Japan's economy is MOST accurate?
DerKrebs [107]

Answer: Japan must import many raw materials for their manufacturing industries.

Explanation:

Japan is an archipelago made up of 6852 islands and surrounded by the Pacific Ocean and various seas. It has limited resources because 73% of the island is mountainous, and only 14% of its territory is an act for agriculture.

Despite this, Japan is a very industrial country, with large companies technological and industrial development. To do this, they export most of the raw materials they use.

Despite the lack of its own raw materials, Japan has the 3rd best economy in the world, with large developed cities, and a multi-service economy.

1)Which generation do you think is the poem addressing to?
Damm [24]

Answer:

1 is the current generation which is Z or maybe the millenials. But maybe more on Z. But it could actually be adressing all generations

2 Environmental destruction is the norm and Families stayed together

Explanation:

reason being that

1First they use some sort of free verse poem cause wow does this not have anything a traditional poem should have. Second, it talks about climate change which only the millenials and Z had issues adressed about it. But there is also "work is more important than family" which adresses the problem of the generation before millenials making the millenials who they are.

2Environmental destruction has been the norm even before the millenials were born and even when it has come to light it is still that, so this poem has a ton of ignorance in it. This era has honestly made more people at home and stayed together literally, if this is being figurative as in the love for family, many eras had families that have not stayed together while this one is honestly not too different just that everyone is more isolated(get the pun).

3The situation is already here so we cannot avoid but face against it or help the nexr. From work being more important than family(boomers) to being apathetic(Z). Situational awareness could help but not much. The only thing we can do is by educating everyone in schools about this. And having our voices be heard as well as finding any method to curb some of the capitalist corruption of our generation. In short, it is inevitable as our past generations, millenials or boomers, never helped us avoid this situation but instead either made it worse or just let it happen.

mojhsa [17]

The pressure from the Southerners for the emergence of newer slave states contributed the most to the division of the Mississippi Territory into two separate states.

<h3>What is the significance of slave states?</h3>

Therefore, the significance regarding slave states has been aforementioned.

Give at least three common motivational techniques from the ""Model of Motivated Learning"" from Learning Theories. Some may cal
inysia [295]

Answer:

Daniel Pink talks about three keys to sustainable motivation: autonomy, mastery and purpose.

Explanation:

1. Autonomy. It is a great motivator, especially when creativity is expected from people. When workers feel they have the ability to choose their projects, where and with whom to work, maximum motivation is achieved.

2. Mastery. We all like to feel competent, learn, grow, master and be expert in some activity. When the activity is aligned with our talents and is challenging, we are deeply motivated. We enter a state called flow, where we lose track of time and have a desire to continue working on the activity.

3. Purpose. People need to feel that they are leaving an imprint, that they are contributing above and beyond themselves. Remind your employees how their work contributes to the whole, how it makes a difference to clients and society.
