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 correct answers to these open questions are the following.
Americans reacted to Sputnik 1 with fear and concern. Yes, United States citizens were concerned that they were inferior to the Soviets in terms of science, technology, and missiles.
Sputnik II Puts Dog In Space?
Yes, it is true. Its name was "Lanka." This dog was launched into space as part of the Soviet Union project Sputnik II, in November of 1957.
The plan for Sputnik II was to make tests and experiments in order to know what was needed to put a human into space.
Who did the Russian choose to send to space?
The Soviet Union decided to send astronaut Yuri Gagarin. He was the first human into space. His capsule was named "Vostok," which completed its orbit on April 12, 1961.
Another response to the launching of Sputnik by the Soviet Union in 1957 was that the US federal government began spending billions of dollars to improve American science education.
The space program had to be sped up because, in those years of the Cold War, it was inadmissible for the United States to behind the Soviet Union in the space race. The United States federal government also invested a lot in education and space research.
Answer:
Her speed was about 3.03 yards per second.
Explanation:
200 yards total in 66 seconds. 200/66 is about 3.03 yards.
I believe the answer is option a
According to studies the correct answer would be <em>children of poverty. </em>Children who were raised in poverty are more likely to have developmental issues, they are often food deprived and are more prone to developing addictions. Where this can also be applied to the other categories, statistics show that poverty is and underlying factor that is crucial for understanding underdeveloped children that are immigrants, adopted or raised by a single parent.
