Standard air flows over a horizontal smooth flat plate at freestream speed U = 20 m/s. Theplate length is L = 1.5 m and its width is b = 0.8 m. The pressure gradient is zero. The boundary layer is tripped so that it is turbulent from the leading edge, the velocity profile is well represented by the 1/7-power expression. Evaluate the boundary layer thickness atthe trailing edge of the plate. Calculate wall shear stress at the trailing edge of the plate. Estimate the skin friction drag on the portion of the plate between × = 0.5 and the trailingedge.
Answers
The estimated skin friction drag on the portion of the plate between x = 0.5 and the trailing edge is 0.542 N.
To determine the boundary layer thickness at the trailing edge of the plate, we need to use the Blasius solution for a flat plate with turbulent boundary layer. The equation for the boundary layer thickness is given by:
δ = 0.37*x / Re_x^(1/5)
where x is the distance along the plate from the leading edge, and Re_x is the Reynolds number at that point, which is given by:
Re_x = U*x / ν
where ν is the kinematic viscosity of air.
At the trailing edge of the plate (x = L = 1.5 m), the Reynolds number can be calculated as:
Re_L = UL / ν = 201.5 / 1.5E-5 = 2E6
Using this value, we can calculate the boundary layer thickness:
δ = 0.37L / Re_L^(1/5) = 0.371.5 / (2E6)^(1/5) = 0.0093 m
To calculate the wall shear stress at the trailing edge, we can use the relation:
τ_w = ρU^2(δ/2)^(-1/7)
where ρ is the density of air. Using the given values, we get:
τ_w = 1.22520^2(0.0093/2)^(-1/7) = 0.678 N/m^2
To estimate the skin friction drag on the portion of the plate between x = 0.5 and the trailing edge, we can use the formula:
D = τ_wb(L-0.5)
where b is the width of the plate. Plugging in the values, we get:
D = 0.6780.8(1.5-0.5) = 0.542 N
Therefore, the estimated skin friction drag on the portion of the plate between x = 0.5 and the trailing edge is 0.542 N.

What are some of the most complex building types to design?.
Answers
A house has all the ingredients that you will find in far more complex buildings. On top of that, they are there in small quantities.
Nearly every house has a kitchen, bathroom, laundry and toilet. You will also find some of these in hospitals, hotels, parking stations, office blocks, sewerage works, defence facilities and so on.
The only difference is that in a house, there may only be one of these and it must be the right size, shape and position so that it is suitable for use. Even the doorways must be positioned correctly - to allow for ventilation, light, privacy , ease of access, safety and even feng-shui.
Each room must be the right size for its’ occupants and its’ usage. Bedrooms should have a window or some other method of providing natural light. Toilets and bathrooms should allow for privacy.
The materials that it is built of should be fit for purpose. The roof should provide shelter from the elements. The walls should be able to support the weight of the roof and provide shelter and security for the occupants. The floor should be stable and strong and able to support the activities that are carried out in the house.
On top of all that, it must look good - to somebody. It also must be comfortable to live in, otherwise the design is a fail. That doesn’t mean that it shouldn’t be cheap to build. A good designer designs with one eye on the asthetics, the other eye on the usage and utility and his hand firmly closed around the cheque-book.

given an integer variable strawsoncamel, write a statement that uses the increment operator to increase the value of that variable by 1.
Answers
To increase the value of an integer variable strawsoncamel by 1 using the increment operator, the following statement can be used strawsoncamel++;
This statement uses the increment operator to increase the value of the variable strawsoncamel by 1. The increment operator (++) is a unary operator which means that it works on a single operand and increases the value of the operand by 1. In this case, the variable strawsoncamel is the operand, and the statement increases its value by 1.
The operator has two forms: pre-increment (++var) and post-increment (var++). In this case, the pre-increment form is used, meaning that the value of strawsoncamel is incremented before the statement is executed.
Incrementing the value of a variable by 1 is a common operation in programming, often used in loops or in situations where a number needs to be increased by a certain amount. The increment operator is a quick and easy way to accomplish this.

the integral of In3x²/×⁵
Answers
If the integral is
\(\displaystyle \int \frac{\ln(3x^2)}{x^5}\,\mathrm dx\)
substitute u = ln(3x ²) and du = 6x/(3x ²) dx = 2/x dx.
Then x ² = exp(u)/3 and x ⁴ = exp(2u)/9.
The integral is transformed to
\(\displaystyle \int \frac{\ln(3x^2)}{x^5}\,\mathrm dx = \int \frac{\ln(3x^2)}{2x^4} \times \dfrac2x \,\mathrm dx \\\\ = \int \frac{u}{2\times\dfrac{e^{2u}}9}\,\mathrm du \\\\ = \frac92 \int ue^{-2u}\,\mathrm du\)
Integrate by parts:
\(f = u \implies \mathrm df = \mathrm du \\\\ \mathrm dg = e^{-2u}\,\mathrm du \implies g = -\dfrac12 e^{-2u}\)
\(\displaystyle \int ue^{-2u}\,\mathrm du = fg - \int g\,\mathrm df \\\\ = -\dfrac12 ue^{-2u} + \displaystyle \frac12 \int e^{-2u}\,\mathrm du \\\\ = -\frac12 ue^{-2u} - \frac14 e^{-2u} + C\)
Then
\(\displaystyle \frac92 \int ue^{-2u}\,\mathrm du = -\frac94 ue^{-2u} - \frac98 e^{-2u} + C\)
which in terms of x would be
\(\displaystyle \int \frac{\ln(3x^2)}{x^5}\,\mathrm dx = -\frac94\times\frac{\ln(3x^2)}{9x^4} - \frac98 \times \frac1{9x^4} + C \\\\ = \boxed{-\frac{\ln(3x^2)}{4x^4}-\frac1{8x^4}+C}\)
A vehicle is being tested using a scan tool. Technician A says that the throttle position (TP) sensor should read between 0 and 1 volt. Technician B says that a factory or factory level scan tool is needed to check for proper voltage and current of the shift solenoids. Which technician is correct?
Answers
Answer: Non of them.
Explanation:
There are many throttle position sensors voltage check. Computer reference voltage to TP sensor is about 5V. Voltage drop should be less than 0.5 v while TP sensor output to computer is about 0.65v.
When a vehicle is being tested using a scan tool, the only the throttle position (TP) sensor that should read between 0 and 1 volt is the base voltage reading. The reading according to specifications is around 0.05v.
When checking for proper voltage for the opening and closing of the throttle, the voltage rises from 1 volt to a maximum of 5 volts.
Ammeter or multimeter can be used to check for proper voltage and current of the shift solenoids.
We can therefore conclude that both technicians A and B are incorrect. This is, non of them is correct.
consider the cascade amplifier of example 1.3. find the overall voltage gain vo/vs obtained when the first and second stages are interchanged. compare this value with the result in example 1.3, and comment/compare the reuslts.Source, stage1, stage2, stage3, Load
Answers
The overall voltage gain of a cascade amplifier is independent of the order of the stages, as long as the voltage gains of the individual stages remain the same.
In a cascade amplifier, the overall voltage gain is obtained by multiplying the voltage gains of the individual stages. When the first and second stages are interchanged, the overall voltage gain changes accordingly.
Let's assume that the voltage gains of the first and second stages are A1 and A2, respectively. The overall voltage gain when the first and second stages are in their original positions is:
Vo/Vs = A1 * A2
When the first and second stages are interchanged, the overall voltage gain becomes:
Vo/Vs = A2 * A1
Since multiplication is commutative, the overall voltage gain remains the same even when the first and second stages are interchanged:
Vo/Vs = A1 * A2 = A2 * A1
Therefore, the overall voltage gain obtained when the first and second stages are interchanged is the same as the overall voltage gain obtained in Example 1.3.
In conclusion, the overall voltage gain of a cascade amplifier is independent of the order of the stages, as long as the voltage gains of the individual stages remain the same.

Answers
Based on the information provided, the soil described as "sandy clay loam" with an "unconfined compressive strength of 1.25 tsf" and being "dug next to a busy highway" can be classified as a cohesive soil type.
Cohesive soils, such as clay, silty clay, and sandy clay, have the ability to stick together due to their fine particle size and cohesive forces. Sandy clay loam specifically indicates a soil composition with a mixture of sand, clay, and silt, where the clay component contributes to its cohesive nature.
The unconfined compressive strength value of 1.25 tsf refers to the maximum stress that the soil can withstand without undergoing significant deformation or failure. This value is typically used as an indicator of the soil's load-bearing capacity.
Being located next to a busy highway suggests that the soil may be subjected to vibrations, traffic loads, and potential disturbances due to construction activities.

Answers
The wired networking standard that specifies the order in which data is sent through the network is Ethernet.
Ethernet is a widely used wired networking standard that defines the protocols and specifications for data transmission over a local area network (LAN). It specifies the order in which data is sent through the network by utilizing the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) algorithm.
The CSMA/CD algorithm ensures that multiple devices connected to an Ethernet network can share the same communication medium without interfering with each other. Before transmitting data, a device using Ethernet listens to the network to detect if it is clear to send data. If the network is busy, it waits for an opportune moment. Once the network is clear, the device sends the data, constantly monitoring for collisions. If a collision occurs (when two or more devices transmit data simultaneously), they stop transmitting, wait for a random period of time, and then retry.
By following this protocol, Ethernet ensures orderly and efficient data transmission within the network, minimizing collisions and maximizing data throughput. It has become the de facto standard for wired local area networks due to its reliability, scalability, and widespread adoption.

Answers
The work done on the gas during this process if the final pressure is 456 kPa is; -82.8 kJ
Workdone in Thermodynamics
We are given;
The initial pressure; P₁ = 96 kPa
Final Pressure; P₂ = 456 kPa
The gas is compressed according to;
p = aV + b
where;
a = -1200 kPa/m³
b = 600 kPa
Thus, at initial pressure P₁ = 96 kPa;
96 = -1200V₁ + 600
1200V₁ = 600 - 95
1200V₁ = 505
V₁ = 505/1200
V₁ = 0.42 m³
At Final Pressure P₂ = 456 kPa;
456 = -1200V₂ + 600
1200V₂ = 600 - 456
1200V₂ = 144
V₂ = 144/1200
V₂ = 0.12 m³
Formula for the workdone during the process is;
W_out = ¹/₂(P₁ + P₂)(V₂ - V₁)

Determine the net energy transfer from the student's body during the 20.00 min ride to school due to electromagnetic radiation. Note: Skin emissivity is 0.90, and the surface area of the student is 1.50m2.
Answers
Answer:
The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.
Explanation:
From Heat Transfer we determine that heat transfer rate due to electromagnetic radiation (\(\dot Q\)), measured in BTU per hour, is represented by this formula:
\(\dot Q = \epsilon\cdot A\cdot \sigma \cdot (T_{s}^{4}-T_{b}^{4})\) (1)
Where:
\(\epsilon\) - Emissivity, dimensionless.
\(A\) - Surface area of the student, measured in square feet.
\(\sigma\) - Stefan-Boltzmann constant, measured in BTU per hour-square feet-quartic Rankine.
\(T_{s}\) - Temperature of the student, measured in Rankine.
\(T_{b}\) - Temperature of the bus, measured in Rankine.
If we know that \(\epsilon = 0.90\), \(A = 16.188\,ft^{2}\), \(\sigma = 1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}}\), \(T_{s} = 554.07\,R\) and \(T_{b} = 527.67\,R\), then the heat transfer rate due to electromagnetic radiation is:
\(\dot Q = (0.90)\cdot (16.188\,ft^{2})\cdot \left(1.714\times 10^{-9}\,\frac{BTU}{h\cdot ft^{2}\cdot R^{4}} \right)\cdot [(554.07\,R)^{4}-(527.67\,R)^{4}]\)
\(\dot Q = 417.492\,\frac{BTU}{h}\)
Under the consideration of steady heat transfer we find that the net energy transfer from the student's body during the 20 min-ride to school is:
\(Q = \dot Q \cdot \Delta t\) (2)
Where \(\Delta t\) is the heat transfer time, measured in hours.
If we know that \(\dot Q = 417.492\,\frac{BTU}{h}\) and \(\Delta t = \frac{1}{3}\,h\), then the net energy transfer is:
\(Q = \left(417.492\,\frac{BTU}{h} \right)\cdot \left(\frac{1}{3}\,h \right)\)
\(Q = 139.164\,BTU\)
The net energy transfer from the student's body during the 20-min ride to school is 139.164 BTU.
