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.

I believe the answer is: Individualism and federal bureaucracy
Individualism becomes a threat because it make people less likely to be involved in social issues, while federal bureaucracy would strengthen the Federal government and would take away the power to determine enacted law from the people.
Answer:
Appearance
Explanation:
Appearance, more than any other factor, has occasioned the objectification of aging. This can have serious consequences on people as they age. Some people might become overly concerned with their looks. Women are particularly affected by this phenomenon. Moreover, people might assume that an older apperance comes with certain decline in cognitive or motor skills, even when the person is still healthy and productive.
<u>Full question:</u>
A major difference between sound recordings made by Emile Berliner and those made by Thomas Edison was that ______.
A. Berliner's disks were flat
B. Edison's disks could be mass produced
C. Edison's disks were coated with lamp black
D. Berliner's disks were made of vinyl
E. None of the above.
<u>Answer:</u>
A major difference between sound recordings made by Emile Berliner and those made by Thomas Edison was that Berliner's disks were flat
<u>Explanation:</u>
Thomas Edison created recorded sound technology, but Emile Berliner's designs began to its mass spread. Berliner flat record disk ultimately supplanted the added flimsy and clumsy Edison cylinders as users' sound technology of preference.
The disk design made flat enhanced the pattern for extent manufactured business sound disks and was the forerunner of nowadays discs patterns. The designated sound-component of the Berliner Collection consists of various disc records generated by the Berliner Gramophone Company. Thomas Edison disk consisted of a thin coating of a phenolic resin
Answer:
Every symptom is not a fever symptom in infants.
Explanation:
Fever occurs when the internal "thermostat" of the body increases the temperature of the body above its normal range.
A child's normal temperature varies with his or her age, activity, and even time of day.
Infants usually have greater levels of temperatures than children of more than 1-2 years. They may have higher temperature during late afternoon and early evening. Temperatures might be low between midnight and early hours of the morning. Checking temperature with palm on the forehead should not be the way to decide if the child has fever. Always use a thermometer to check body's temperature and conclude whether it is fever or not.
