Question

**List three principale parameters of atmospheric boundary
layer?**

Answer #1

Explain an example of how a fish manipulates its boundary layer
to reduce drag.

What considerations are taken to consider the analysis of the
boundary layer? Explain widely.
topic of mechanic of fluids.

In a lab experiment for a flat plate zero-pressure gradient
boundary layer it is desired to find the friction coefficient (Cf)
at location x=1 m from the leading edge of the plate. In order to
do this, the momentum thickness of the boundary layer is measured
at two locations 0.005m on either side of x=1m. the momentum
thickness is measured to be 1.638 mm at x=0.995m and 1.652mm at
x=1.005m, respectively, when the approach or free-stream velocity
is 5m/s.

Explain the mass transfer in the laminar boundary layer when the
fluid is in laminar flow over a flat plate.

4.8 In what sense are the potential flow solutions and the
boundary-layer flow solutions
complementary?

Given: an atmospheric layer. Height is 5650 m, temperature is
-61◦C, pressure is 515 hPa, density is 0.678 kg m−3 , constant
vertical velocity of 9.8 cm s−1 . Over 20 minutes, atmospheric flow
between the 5650 m and 7745 m surfaces generates layer mean
temperature advection of 1.9◦C hr−1 . Calculate the pressure for
the 5650 m level after the 20 minutes have passed. With the
assumption that atmospheric flow is geostrophic.

Found the boundary layer flow on the flow through the flat plate
in the water tunnel. The length of the plate is, L = 30 cm and
width b = 1 m. Meanwhile freestream speed is, U = 2 m / s with the
speed profile is parabolic and. Draw, and the x / L, by formulating
it !

Write a Python function called sumNxN with
three parameters. The first parameter is a nested list (matrix)
representing a matrix of size N x N. The second parameter is the
integer N, and the third is a list of N zeros.
Modify the list of zeros so that each entry is the sum of the
corresponding column. There is no return.
Note: You may assume the sizes provided are all correct.

Carbon dioxide at 90 C and atmospheric pressure flows over a
square horizontal plate at 60 m/s. The side lengths are 60 cm, and
the plate is maintained at a constant uniform temperature of 10 C.

thickness at the center of the plate?
