Bridges use MAC addresses to determine whether to forward traffic.

MAC (Media Access Control) addresses are unique identifiers assigned to network interface controllers (NICs) by the manufacturer. These addresses are used in Ethernet and Wi-Fi networks to uniquely identify devices at the hardware level. A MAC address is a 48-bit (6-byte) hexadecimal value, typically displayed in the format of six groups of two hexadecimal digits separated by colons or hyphens (e.g., 00:1A:2B:3C:4D:5E). They maintain a table of MAC addresses and corresponding ports, and use this information to decide where to send incoming traffic. They do not rely on IP addresses or traffic conditions at the time, and they do not forward all traffic indiscriminately.

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53

Answer:

The volume percentage of graphite is 10.197 per cent.

Explanation:

The volume percent of graphite is the ratio of the volume occupied by the graphite phase to the volume occupied by the graphite and ferrite phases. The weight percent in the cast iron is 3.2 wt% (graphite) and 96.8 wt% (ferrite). The volume percentage of graphite is:

\(\%V_{gr} = \frac{V_{gr}}{V_{gr}+V_{fe}} \times 100\,\%\)

Where:

\(V_{gr}\) - Volume occupied by the graphite phase, measured in cubic centimeters.

\(V_{fe}\) - Volume occupied by the graphite phase, measured in cubic centimeters.

The expression is expanded by using the definition of density and subsequently simplified:

\(\%V_{gr} = \frac{\frac{m_{gr}}{\rho_{gr}} }{\frac{m_{gr}}{\rho_{gr}}+\frac{m_{fe}}{\rho_{fe}}}\times 100\,\%\)

Where:

\(m_{fe}\), \(m_{gr}\) - Masses of the ferrite and graphite phases, measured in grams.

\(\rho_{fe}, \rho_{gr}\) - Densities of the ferrite and graphite phases, measured in grams per cubic centimeter.

\(\%V_{gr} = \frac{1}{1+\frac{\frac{m_{fe}}{\rho_{fe}} }{\frac{m_{gr}}{\rho_{gr}} } }\times 100\,\%\)

\(\%V_{gr} = \frac{1}{1 + \left(\frac{\rho_{gr}}{\rho_{fe}} \right)\cdot\left(\frac{m_{fe}}{m_{gr}} \right)} \times 100\,\%\)

If \(\rho_{gr} = 2.3\,\frac{g}{cm^{3}}\), \(\rho_{fe} = 7.9\,\frac{g}{cm^{3}}\), \(m_{gr} = 3.2\,g\) and \(m_{fe} = 96.8\,g\), the volume percentage of graphite is:

\(\%V_{gr} = \frac{1}{1+\left(\frac{2.3\,\frac{g}{cm^{3}} }{7.9\,\frac{g}{cm^{3}} } \right)\cdot \left(\frac{96.8\,g}{3.2\,g} \right)} \times 100\,\%\)

\(\%V_{gr} = 10.197\,\%V\)

The volume percentage of graphite is 10.197 per cent.

Following are the solution to the given points:

\(\to C_{Gr} = 100\\\\ \to C_{\alpha}= 0\)From \(Fe-F_{\frac{e}{3}} c\) diagram.  

\(\to W_{\alpha} =\frac{C_{Gr}-C_{o}}{C_{Gr}-C_{\alpha}}\)

           \(= \frac{100-3.6}{100-0} \\\\= \frac{100-3.6}{100} \\\\= \frac{96.4}{100} \\\\=0.964\)

Calculating the weight fraction of graphite:  

\(\to W_{Gr}=\frac{C_0 - c_d}{C_{Gr} -c_d}\)

            \(= \frac{3.6-0}{100-0} \\\\ = \frac{3.6}{100} \\\\= 0.036\)

Calculating the volume percent of graphite:

\(\to V_{Gr}=\frac{\frac{W_{Gr}}{P_{Gr}}}{\frac{w_{\alpha}}{P_{\alpha}}+ \frac{W_{Gr}}{P_{Gr}}}\)

           \(=\frac{\frac{0.036}{2.3}}{\frac{0.964}{7.9}+\frac{0.036}{2.3}}\\\\=0.11368 \times 100\%\\\\=11.368\%\)

Therefore, the final answer is "0.964, 0.036, and 11.368%"

The process of heating a metal after cold working to relieve internal stress and decrease dislocation density is known as annealing.

Annealing is a heat treatment process used to modify the physical and sometimes chemical properties of a material. It is typically used to induce ductility, soften material, improve machinability, and/or help improve cold working properties.

The annealing process requires a recrystallization temperature within a specified time before the cooling process is carried out. The cooling rate depends on the type of metal being annealed. For example, ferrous metals such as steel are usually cooled to room temperature in still air, while copper, silver, and brass are quenched slowly in air or rapidly cooled with water.

[b]. the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

Explanation:

Atoms are referred to be the smallest units of a substance although it can be sub-divided into smaller units such as proton, neutron and electron. When atoms combines in group they form a molecule.

From the question above it is seen that two substances were mixed together to give two ending substances that is:

substance A [ colorless liquid with a strong smell] + substance B[white solid with no smell] ---------> substance C[ repeating group of atoms shown above on the right] + substance D.

The ending substance that is, substance C is the same substance as substance A which is the colorless liquid with a strong smell.

When the substance A reacted with substance B, it gives substance C and D that is the ending substances are the products of the reaction between A and B.

Hence, the substance with colorless liquid with a strong smell and a white solid with no smell are being used up to produce the ending substance had the repeating group of atoms shown above on the right and the other ending substance.

This question is incomplete, the complete question is;

For a steel alloy it has been determined that a carburizing heat treatment of 11.3 h duration at Temperature T1 will raise the carbon concentration to 0.44 wt% at a point 1.8 mm from the surface. A separate experiment is performed at T2 that doubles the diffusion coefficient for carbon in steel.

Estimate the time necessary to achieve the same concentration at a 4.9 mm position for an identical steel and at the same carburizing temperature T2.

Answer:

the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Explanation:

Given the data in the question;

treatment time t₁ = 11.3 hours

Carbon concentration = 0.444 wt%

thickness at surface x₁ = 1.8 mm = 0.0018 m

thickness at identical steel x₂ = 4.9 mm = 0.0049 m

Now, Using Fick's second law inform of diffusion

\(x^2\) / Dt = constant

where D is constant

then

\(x^2\) / t = constant

\(x^2_1\) / t₁ = \(x^2_2\) / t₂

\(x^2_1\) t₂ = t₁\(x^2_2\)

t₂ = t₁\(x^2_2\) / \(x^2_1\)

t₂ = (\(x^2_2\) / \(x^2_1\))t₁

t₂ = \((\) \(x_2\) / \(x_1\) \()^2\) × t₁

so we substitute

t₂ = \((\) 0.0049  / 0.0018  \()^2\) × 11.3 hrs

t₂ = 7.41 × 11.3 hrs

t₂ = 83.733 hrs

Therefore, the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Answer:

LOS = A

Explanation:

Given all the parameters the level of service as seen from the attached graph

is LOS =  A

To determine the LOS from the attached graph

calculate the trial value of Vp

Vp = V / PHF

     = (100 + 150) / 0.95  =  263 pc/h

since the trial value of Vp = ( 0 to 600 ) pc/h . hence E.T = 1.7 , ER = 1

next we will calculate the flow rate

flow rate = 1 / [ ( 1 + PT(ET - 1 ) + PR ( ER - 1 ) ]

             Fhr  = 1 / 1.035 = 0.966 ≈ 1

next calculate the real value of Vp

Vp = V / ( PHF * N * Fhr * Fp )

     = ( 100 + 150 ) / ( 0.95 * 2 * 1 * 1 )

Vp ≈ 126 pc/h/In

Next calculate the density

D = Vp /  S  =  126 / ( 45 * 1.61 )  = 1.74 pc/km/In
