At a certain location, wind is blowing steadily at 7 m/s. Determine the mechanical energy of air per unit mass and the power generation potential of a wind turbine with 80-m-diameter blades at that location. Also determine the actual electric power generation assuming an overall efficiency of 30 percent. Take the air density to be 1.25 kg/m3.
Answer:
Explanation:
From the information given;
The velocity of the wind blow V = 7 m/s
The diameter of the blades (d) = 80 m
Percentage of the overall efficiency \(\eta_{overall} = 30\%\)
The density of air \(\rho = 1.25 kg/km^3\)
Then, we can use the concept of the kinetic energy of the wind blowing to estimate the mechanic energy of air per unit mass by using the formula:
\(e_{mechanic} = \dfrac{mV^2}{2}\)
here;
m = \(\rho AV\)
= \(1.25 \times \dfrac{\pi}{4}(80)^2 \times 7\)
= 43982.29 kg/s
∴
\(W = e_{mechanic} = \dfrac{mV^2}{2}\)
\(= \dfrac{43982.29 \times 7^2}{2}\)
\(= 1077566.105 \ W\)
\(\mathbf{ =1077.566 \ kW}\)
The actual electric power is:
\(W_{electric} = \eta_{overall} \times W\)
\(W_{electric} = 0.3 \times 1077.566\)
\(\mathbf{W_{electric} =323.26 \ kW}\)

What is DNS?
DNS, or Domain Name System, is an internet protocol used to translate domain names, such as www.example.com, into IP addresses, such as 192.168.2.1, that computers can understand and use to communicate with each other. DNS acts as a directory service, providing a link between domain names and their associated IP addresses, which are stored and managed in a distributed database system. DNS is essential for the functioning of the internet, allowing users to access websites and services without having to remember their numerical IP addresses. DNS works by querying a distributed network of DNS servers, which maintain a database of IP addresses and their corresponding domain names. When a DNS query is made, the DNS server looks up the requested IP address in its database and returns it to the user. DNS is an important part of the internet infrastructure and is used by many different types of services, such as email, web hosting, and streaming services.

An evanescent field at angular frequency w = 10¹5 rad/s is created via total internal reflection at the interface between two different media with refractive index n1 and n2, where n1-4, and n2=2. The incident angle 0₁-80°. We can define the propagation direction of the evanescent field as the x-direction, and the z-direction is normal to the interface between the two media, and therefore the evanescent field wave function can be expressed as Ee(kxx+k₂z-t) (a) Should the incident light come from the medium with n1 or the medium with n2 to undergo total internal reflection? (b) is the evanescent field in the medium with n1 or the medium with n2? (c) Calculate the values for kx and kz in the medium in which the field is evanescent.
The incident light should come from the medium with n2 to undergo total internal reflection.
(a) The incident light should come from the medium with n2 to undergo total internal reflection. Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index and the angle of incidence exceeds the critical angle. In this case, since n2 is smaller than n1, the light should originate from the medium with n2 to experience total internal reflection at the interface.
(b) The evanescent field is present in the medium with n1. After total internal reflection, the incident light is completely reflected back into the medium with n1, and it does not propagate into the medium with n2. As a result, the evanescent field is confined to the medium with n1.
(c) To calculate the values of kx and kz in the medium where the field is evanescent, we can use the relationship between the wave vector (k) and the refractive index (n) in each medium. The wave vector in the x-direction (kx) and the wave vector in the z-direction (kz) can be expressed as follows:
kx = (w/c) * n * sin(0₁)
kz = [(w/c)^2 * \(n^2\) - \(kx^2\)]
where:
w = angular frequency of the evanescent field
c = speed of light in vacuum
n = refractive index of the medium
0₁ = angle of incidence
Given:
w = 10¹⁵ rad/s
n1 = 4
n2 = 2
0₁ = 80°
Using the above equations, we can calculate the values of kx and kz in the medium with n1:
kx = (10¹⁵ rad/s / 3x10^8 m/s) * 4 * sin(80°)
kz = [(10¹⁵ rad/s / 3x10^8 m/s) * 4^2 - kx]
After substituting the values and performing the calculations, we can determine the specific values of kx and kz in the medium with n1.

Five bolts are used in the connection between the axial member and the support. The ultimate shear strength of the bolts is 320 MPa, and a factor of safety of 4.2 is required with respect to fracture. Determine the minimum allowable bolt diameter required to support an applied load of P
Answer:
The minimum allowable bolt diameter required to support an applied load of P = 450 kN is 45.7 milimeters.
Explanation:
The complete statement of this question is "Five bolts are used in the connection between the axial member and the support. The ultimate shear strength of the bolts is 320 MPa, and a factor of safety of 4.2 is required with respect to fracture. Determine the minimum allowable bolt diameter required to support an applied load of P = 450 kN"
Each bolt is subjected to shear forces. In this case, safety factor is the ratio of the ultimate shear strength to maximum allowable shear stress. That is to say:
\(n = \frac{S_{uts}}{\tau_{max}}\)
Where:
\(n\) - Safety factor, dimensionless.
\(S_{uts}\) - Ultimate shear strength, measured in pascals.
\(\tau_{max}\) - Maximum allowable shear stress, measured in pascals.
The maximum allowable shear stress is consequently cleared and computed: (\(n = 4.2\), \(S_{uts} = 320\times 10^{6}\,Pa\))
\(\tau_{max} = \frac{S_{uts}}{n}\)
\(\tau_{max} = \frac{320\times 10^{6}\,Pa}{4.2}\)
\(\tau_{max} = 76.190\times 10^{6}\,Pa\)
Since each bolt has a circular cross section area and assuming the shear stress is not distributed uniformly, shear stress is calculated by:
\(\tau_{max} = \frac{4}{3} \cdot \frac{V}{A}\)
Where:
\(\tau_{max}\) - Maximum allowable shear stress, measured in pascals.
\(V\) - Shear force, measured in kilonewtons.
\(A\) - Cross section area, measured in square meters.
As connection consist on five bolts, shear force is equal to a fifth of the applied load. That is:
\(V = \frac{P}{5}\)
\(V = \frac{450\,kN}{5}\)
\(V = 90\,kN\)
The minimum allowable cross section area is cleared in the shearing stress equation:
\(A = \frac{4}{3}\cdot \frac{V}{\tau_{max}}\)
If \(V = 90\,kN\) and \(\tau_{max} = 76.190\times 10^{3}\,kPa\), the minimum allowable cross section area is:
\(A = \frac{4}{3} \cdot \frac{90\,kN}{76.190\times 10^{3}\,kPa}\)
\(A = 1.640\times 10^{-3}\,m^{2}\)
The minimum allowable cross section area can be determined in terms of minimum allowable bolt diameter by means of this expression:
\(A = \frac{\pi}{4}\cdot D^{2}\)
The diameter is now cleared and computed:
\(D = \sqrt{\frac{4}{\pi}\cdot A}\)
\(D =\sqrt{\frac{4}{\pi}\cdot (1.640\times 10^{-3}\,m^{2})\)
\(D = 0.0457\,m\)
\(D = 45.7\,mm\)
The minimum allowable bolt diameter required to support an applied load of P = 450 kN is 45.7 milimeters.
We have that the minimum allowable bolt diameter is mathematically given as
d = 26.65mmFrom the question we are told
Five bolts are used in the connection between the axial member and the support. The ultimate shear strength of the bolts is 320 MPa, and a factor of safety of 4.2 is required with respect to fracture. Determine the minimum allowable bolt diameter required to support an applied load of Assuming P to be P = 425 kN.DiameterGenerally the equation for the stress is mathematically given as
\(\mu= 320/4.2 \\\\\mu= 76.190 N/mm^2\)
Therefore
Force = Stress * area
Force = P/2
F= 425,000 N / 2 = 212,500 N
Hence area of each bolt is given as
212,500 = 76.190*( 5* area of each bolt)
area of each bolt = 557.815
Since
area of each bolt=\pi*d^2/4
\pi*d^2/4 = 557.815

Answer:
299.36 feet
Explanation:
\(To \ find \ the \ distance \ of \ the \ ball \ from \ the \ home \ plate. \\ \\ From \ the \ given \ information:\)
\(Height \ h = 4 \ ft\)
\(Initial \ speed \ V_o = 98 \ ft/s ec\)
\(The \ angle \ \theta = 45^0\)
\(Acceleration \ due \ to \ gravity (g)= 32.2 \ ft/s\)
\(U_x = V_o \ cos 45 = \dfrac{98}{\sqrt{2}}\)
\(U_y = V_o \ sin 45 = \dfrac{98}{\sqrt{2}}\)
So;
\(S_y = u_y t - \dfrac{1}{2}gt^2\)
\(-1 =\dfrac{98}{\sqrt{2}}t - \dfrac{1}{2}*32*1.85t^2\)
By solving:
\(t_1 = 4.32 \ sec\)
Thus;
\(horizontal \ distance = U_x t\)
\(= \dfrac{98}{\sqrt{2}}\times 4.32\)
\(\mathbf{=299.36 \ feet}\)
\(\mathbf{Thus \ , the \ distance \ from \ the \ home \ plate \ = \ 299.36 \ feet}\)

Therefore, it is essential to remove such tools from use to ensure safety and maintain efficiency.
When the heads of impact tools like chisels are damaged, they can lead to a loss of control and accuracy during operation. A damaged head may cause the tool to slip, resulting in unintended cuts or injuries to the user. Moreover, worn heads can reduce the effectiveness of the tool, requiring more force to achieve the desired results. This increased force can strain the user's muscles and joints, leading to fatigue and potential long-term injuries.
By removing impact tools with damaged or worn heads from use, the risk of accidents and injuries can be significantly reduced. Regular inspection and maintenance of these tools are crucial to identify any signs of wear or damage early on. If a chisel or any other impact tool is found to have a damaged head, it should be promptly replaced or repaired by a qualified professional.

A PFAS anchorage point for a 6-foot lanyard must be able to hold a minimum static load of 5,000 pounds.
PFAS stands for Personal Fall Arrest System, which is a type of fall protection equipment that is designed to protect workers from falls.
The 5,000-pound minimum static load requirement is based on the assumption that the PFAS will experience a shock load of 2,500 pounds in the event of a fall.
This shock load is due to the force of the fall and the weight of the worker, and it puts a significant amount of stress on the anchorage point. The 5,000-pound minimum static load ensures that the anchorage point can withstand this shock load without failing.
It's important to note that the 5,000-pound minimum static load requirement is a general guideline, and the actual load capacity of the anchorage point will depend on a variety of factors, including the type of anchorage point, the material it's made from, and the conditions of use.

What is local area network?A local area network is a type of computer network that connects computers in an area that is relatively small, like a home, school, lab, university campus, or office building. On the other hand, a wide area network often makes use of leased telecommunications circuits and covers a larger geographic area. A local area network (LAN) is a network made up of several computers that are connected in one location.Through TCP/IP ethernet or Wi-Fi, the computers in a LAN are linked to one another. An organisation, whether a school, office, association, or church, typically has its own LAN. Local area network is what it means.To learn more about local area network, refer to:

write down the tracking error such that the adaptive cruise control objective is satisfied.
Answer:
The most common reason a cruise control stops working is due to a blown fuse or a defective brake pedal switch. It can also be caused by issues with the throttle control system or the ABS. In older cruise control systems it can be caused by a broken vacuum line.
Steam with specific enthalpy of 3278kj/kg goes through nozzle at station A velocity of 20m\s. If the exit area of the nozzle are adiabatic, find enthalpy per kg of steam leaving nozzle of steam is incompressible
If the steam is incompressible, it means that its specific volume remains constant throughout the process. In this case, the enthalpy per kilogram of steam leaving the nozzle will also remain constant.
Given that the specific enthalpy of the steam at station A is 3278 kJ/kg and the velocity at station A is 20 m/s, we can calculate the enthalpy per kilogram of steam leaving the nozzle.
The enthalpy per kilogram of steam leaving the nozzle can be determined using the specific enthalpy equation:
h2 = h1 + (V1^2 - V2^2)/2
Where:
h1 = specific enthalpy at station A
h2 = specific enthalpy at the exit of the nozzle
V1 = velocity at station A
V2 = velocity at the exit of the nozzle
Since the steam is incompressible, the specific volume remains constant. Therefore, the velocity at the exit of the nozzle, V2, can be calculated using the equation:
V2 = V1 * (A1/A2)^0.5
Where:
A1 = cross-sectional area at station A
A2 = cross-sectional area at the exit of the nozzle
Since the exit area of the nozzle is adiabatic, the cross-sectional area at the exit remains the same as the cross-sectional area at station A (A1 = A2).
Substituting the given values into the equations, we can calculate the enthalpy per kilogram of steam leaving the nozzle:
V2 = V1 * (A1/A2)^0.5
V2 = 20 m/s * (1/1)^0.5
V2 = 20 m/s
h2 = h1 + (V1^2 - V2^2)/2
h2 = 3278 kJ/kg + (20^2 - 20^2)/2
h2 = 3278 kJ/kg
Therefore, the enthalpy per kilogram of steam leaving the nozzle is 3278 kJ/kg, assuming the steam is incompressible.
