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.

Jim Crow laws were state and local laws that enforced racial segregation in the southern United States. These laws were enacted in the late 19th and early 20th centuries by white southern democrat dominated state legislatures to disenfranchise and remove political and economic gains made by black people during the reconstruction period.
Answer:
A. One-sample z-test for a mean
Explanation:
took the test and got a 98%
Answer:
Exponential growth
Explanation:
Exponential growth (sometimes called the log phase) is a type of population growth where bacteria are regularly doubling, uninhibited by any limitations such as nutrient availability. During exponential growth, the population will double at each interval of time, and therefore the rate of increase doubles at each interval.
Exponential growth is only part of the life of a bacterial population. Eventually, space/nutrient availability will drop and the waste products will rise, and the growth of the population will cease.
