Karl von baer also lent proof toa theory of evolution. what did he do

Social Studies
1 answer:
zmey [24]3 years ago
3 0

Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.

His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.

The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.

How do you find the boundary layer thickness of a pipe?
QveST [7]

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.
