Answer:
The thickness of the layer increases as the flow progresses along the surface and the flow nature changes from laminar to turbulent until finally the fluid separates from the body.
Explanation:
The thickness of the boundary layer depends on it's distance from the leading edge of the body with thickness increasing along the flow. This can be attributed to the viscosity of the fluid that acts as a messenger that propagates the disturbance from the surface until the thickness where the velocity of fluid approaches the flow velocity of free stream.
Also the nature of the flow changes from laminar to turbulent which is attributed to the variation in the leading edge distance.

Detailed solution is given in attached image
Answer:
q=39.15 W/m²
Explanation:
We know that
Thermal resistance due to conductivity given as
R=L/KA
Thermal resistance due to heat transfer coefficient given as
R=1/hA
Total thermal resistance
Now by putting the values
We know that
Q=ΔT/R
So heat transfer per unit volume is 39.15 W/m²
q=39.15 W/m²
Answer:
Explanation:
A.)
You just pick values for x, y and z, then work out F for each case. Since you have four variables, the values for x, y and z in your table will be as follows:
w x y z
0 0 0 0
0 0 0 1
0 0 1 0
0 0 1 1
0 1 0 0
0 1 0 1
0 1 1 0
0 1 1 1
1 0 0 0
1 0 0 1
1 0 1 0
1 0 1 1
1 1 0 0
1 1 0 1
1 1 1 0
1 1 1 1
Now just work out F for each case. It would be helpful to add a few extra coloumns since that's a pretty big equation. Here's how I would do it (notice the titles of the columns. I've worked out the first two for you to help you understand)
w | x | y | z | xy'z | x?y?z | w?xy | wx?y | wxy | F
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0
0 | 0 | 0 | 1 | 0 | 1 | 0 | 0 | 0 | 1

C.)
F = xy'z + x'y'z + w'xy + wx'y + wxy
F = (x+x')(y'z) + w'xy + (x+x')(wy)
F = y'z + w'xy + wy
F = y'z + y(w'x + w)
F = y'z + y(w + x)
F = y'z + wy + xy

Logic Circuits, Boolean Algebra, and Truth Tables
: Truth Tables
A truth table is a chart of 1s and 0s arranged to indicate the results (or outputs) of all possible inputs. The list of all possible inputs are arranged in columns on the left and the resulting outputs are listed in columns on the right. There are 2 to the power n possible states (or combination of inputs). For example with three inputs there are 2^3=8 possible combination of inputs. (Audio)
E)
: Logic Diagram
A logic diagram uses the pictoral description of logic gates in combination to represent a logic expression. An example below shows a logic diagram with three inputs (A, B, and C) and one output (Y). The interpretation of this will become clear in the following sections.
