An airplane flying across the sky experience drag force determined by the factors including the speed of flight, coefficient of skin friction and the reference surface area

The boundary layer thickness is approximately 0.233 cm

The total skin friction drag, is approximately 265 N

Reason:

First part:

Given parameters are;

Chord length, L = 3 m

Velocity of the plane, V = 200 m/s

Density of the air, ρ = 1.225 kg/m³

Viscosity of the air, μ = 1.81 × 10⁻⁵ kg/(m·s)

The Reynolds number is given as follows;

\(R_{eL} = \dfrac{\rho \times V \times L}{\mu}\)

Therefore;

\(R_{eL} = \dfrac{1.255 \times 200 \times 3}{1.81 \times 10^{-5}} = 4.16022099448 \times 10^7 \approx 4.16 \times 10^7\)

Boundary layer thickness, \(\delta_L\), for laminar flow, is given as follows;

\(\dfrac{ \delta_L }{L}=\dfrac{5.0}{\sqrt{R_{eL} } }\)

\({ \delta_L }=\dfrac{5.0 \times L}{\sqrt{R_{eL} } }\)

Which gives;

\({ \delta_L }=\dfrac{5.0 \times 3}{\sqrt{4.16 \times 10^{7}} } \approx 2.33 \times 10^{-3 }\)

The boundary layer thickness, \(\delta_L\) ≈ 2.33 × 10⁻³ m = 0.233 cm

Second Part

The total skin friction is given as follows;

\(Dynamic \ pressure, q = \dfrac{1}{2} \cdot \rho \cdot V^2\)

Therefore;

\(q = \dfrac{1}{2} \times 1.225 \times 200^2 = 24,500\)

The dynamic pressure, q = 24,500 N/m²

Skin friction drag coefficient, \(C_D\), is given as follows;

\(C_D = \dfrac{1.328}{\sqrt{R_{eL} } }\)

Therefore;

\(C_D = \dfrac{1.328}{\sqrt{4.16 \times 10^7 } } \approx 2.06 \times 10^{-4}\)

Skin friction drag, \(D_f\), is given as follows;

\(D_f\) = q × \(C_D\) × A

Where;

A = The reference area

∴ \(D_f\) = 24,500 N/m² × 2.06 × 10⁻⁴ × 3 m × 17.5 m = 264.9675 N ≈ 265 N

The total skin friction drag, \(D_f\) ≈ 265 N

7 x 3 = 21 divded by 10 is 2

so now we have 14

The sinusoids corresponding to each of the given phasors are a) V = 57.72 + j51.91,b) V = 6 + j8,c) I1 ≈ -1.4 - j2.42,d) I2 = -0.5 - j1.2.

To find the sum of V1 and V2, we need to add their phasors. Phasors are complex numbers that represent sinusoidal signals.

a) For V1 = 60 <15°, we can represent it as V1 = 60e^(j15°).

  Similarly, for V2 = 6+j8, we can write it in polar form as V2 = 10e^(j53.13°) since the magnitude is sqrt(6^2 + 8^2) = 10 and the angle is tan^(-1)(8/6) ≈ 53.13°.

b) To find the sum V = V1 + V2, we can add their phasors:

  V = V1 + V2 = 60e^(j15°) + 10e^(j53.13°).

  To simplify the expression, we can convert the phasors to rectangular form:

  V = 60(cos(15°) + jsin(15°)) + 10(cos(53.13°) + jsin(53.13°)).

  Expanding and combining the real and imaginary parts:

  V = 60cos(15°) + 10cos(53.13°) + j(60sin(15°) + 10sin(53.13°)).

  Evaluating the trigonometric functions:

  V ≈ 57.72 + j51.91.

  Therefore, V = 57.72 + j51.91.

c) For I1 = 2.8e^(-jπ/3), we have I1 ≈ 2.8(cos(-π/3) + jsin(-π/3)).

  In rectangular form: I1 ≈ 2.8(-0.5 - j0.866).

  Therefore, I1 ≈ -1.4 - j2.42.

d) For I2 = -0.5 - j1.2, there is no need for conversion since it is already given in rectangular form.

In summary, the sinusoids corresponding to each of the given phasors are:

a) V = 57.72 + j51.91

b) V = 6 + j8

c) I1 ≈ -1.4 - j2.42

d) I2 = -0.5 - j1.2

Answer:

If 60% of the encryption operations can be performed in parallel in the original program, then adding a second unit would provide a speedup of 20 on the encryption operation portion that can be parallelized. This is because the second unit allows for the parallel execution of the encryption operations, resulting in a reduction of the execution time.

On the other hand, if the parallelization is limited to the number of encryption units, providing four encryption units would provide a speedup of 10 on the operation portion that cannot be parallelized. This is because the addition of two more units would not increase the parallelization of the encryption operations that are not parallelizable.

Therefore, if the goal is to speed up the encryption operation as much as possible, adding a second unit to support parallel encryption operations would be more useful as it would provide a speedup of 20 on the encryption operation portion that can be parallelized.

The addition of a second unit to facilitate parallel encryption operations would be more beneficial if the goal is to accelerate the encryption process.

If 60% of the encryption processes in the original program can be carried out in parallel, adding a second unit would result in a speedup of 20 for that portion of the encryption procedures that can be parallelized.

This is so that the execution time can be decreased by doing the encryption procedures in parallel using the second unit.

The provision of four encryption units would result in a 10x speedup on the operation portion that cannot be parallelized, however, assuming the number of encryption units is the only constraint on parallelization.

This is so that the parallelization of the encryption processes that cannot be parallelized would not be increased by the addition of two more units.

Therefore, if the intention is to speed up the encryption process, adding a second unit to enable parallel encryption operations would be more advantageous.

If Reynolds number increases the extent of the region around the object that is affected by viscosity decreases.

Explanation:

Reynolds number is an important dimensionless parameter in fluid mechanics.

It is calculated as;

\(R_e__N} = \frac{\rho vd}{\mu}\)

where;

ρ is density

v is velocity

d is diameter

μ is viscosity

All these parameters are important in calculating Reynolds number and understanding of fluid flow over an object.

In aerodynamics, the higher the Reynolds number, the lesser the viscosity plays a role in the flow around the airfoil. As Reynolds number increases, the boundary layer gets thinner, which results in a lower drag. Or simply put, if Reynolds number increases the extent of the region around the object that is affected by viscosity decreases.

Explanation:

member AB:

-800( 4/3 ) + Nb (2) = 0

Nb (2) = 3200/3

Nb = 533.3N

Post BC:

summation of force along the y axis=0

Nc + Nb + 150(3/5 ) -50(9.81)=0

Nc + 533.3 + 150(3/5 ) -50(9.81)=0

Nc = 933.83 N

Also (-4/5)(150)(3) + Fb(0.7)= 0

Fb = (4/5)(150)(3)/0.7 = 51.429 N

Likewise alog the x axis,

4/5(150) - Fc -Fb = 0

4/5(150) - Fc -51.429 = 0

Fc = 4/5(150)  -51.429 =68.571 N

Answer:

a)\(V_1=4.88m^2/s\)

  \(V_2=4.88m^2/s\)

b)\(P=-119.18kW\)

Explanation:

From the question we are told that:

Steady State Saturated vapor \(T_1= -20C=>253k\)

Mass Flow rate \(M=1.2kg/s\)

Exit Pressure \(P_2=7bar\)

Exit Temperature \(T_2=70C=>373k\)

From Refrigerant 134a Properties

\(T_1= -20C =>P_1=1.399 bar\)

Generally the equation for Volumetric Flow rate is mathematically given by

For Inlet

\(V_1=m\frac{RT_1}{P_1}\)

\(V_1=m\frac{8314*253}{1.399*10^3}\)

\(V_1=18.97m^2/s\)

For outlet

\(V_2=m\frac{RT_2}{P_2}\)

\(V_2=1.2*\frac{8314*343}{7*10^3}\)

\(V_2=4.88m^2/s\)

b)

Generally the equation for Steady state mass and energy equation  is mathematically given by

\(P=m(h_1-h_2)\)

From Refrigerant 134a Properties

\(T_1= -20C =>h_1=24.76kJ/kg\)

\(T_2= 70C =>h_2=124.08kJ/kg\)

Therefore

\(P=1.2(12.76-124.08)\)

\(P=-119.18kW\)

40.7465 \(ft^2\)

Explanation:

The first step for solving this problem is to convert the units from gallons to cubic feet and from millimeters to cubic feet:

1 gallon = 0.133681 cubic feet

10 mm = 0.001 m = 0.0032808 ft

The second step is to divide the volume (the gallon of paint) by the coat thickness. This returns the area.

\(A = \frac{Volume}{thickness}=\frac{0.133681ft^3}{0.0032808ft}=40.7465 ft^2\)

This is the approximate area that the gallon of paint will be able to cover.
