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:
Ghatasthapana is a highly significant ritual in Navratri celebrations as Ghata or Kalash or the sacred pot is the major object of worship during Navratri. It is in this pot that Goddess Shakti is invoked for nine days and this pot is then worshipped daily till the ninth day.
Explanation:
<span>some land formations in California formed by the erosion were : Seaside cliffs and wetlands
Seaside cliffs formed by the abrasion of waves that deteriorate the land little by little which eventually formed the seacliff, meanwhile wetlands are formed as a physical barrier to counter the erosion. Yosemite National park and lakes in California were actually formed by erosion.</span>
Answer: Repetitive-part learning
Explanations: Repetitive-part learning can be simply defined as a method used in learning new skills where an individual learns a part of the skill and practice, then a second part of the skill is learned, part one and two are combined together and practiced and then a third part is introduced which has to be learned and combined with the previous ones and practiced, the process will continue in this sequence untill all part are learned, combined and practised as a whole and mastered.
This allows individuals to learn the small details in each skills.
Dividing the golf swing skill acquisition into different components and having his students learn each component independently before combining all the components to practice a complete golf swing is a good illustration of Repetitive-part learning.
