The critical cooling rate of steels refers to the minimum rate at which a steel alloy must be cooled to achieve a fully martensitic structure during quenching. The addition of certain alloying elements can enhance the hardenability and reduce the critical cooling rate, allowing for the formation of martensite during quenching.

The critical cooling rate is influenced by several factors, including the chemical composition of the steel and the presence of alloying elements. The addition of alloying elements can significantly affect the critical cooling rate. Increasing the carbon content in steel increases the hardenability, which is the ability of the steel to form martensite upon quenching. Alloying elements such as chromium, molybdenum, and nickel can also enhance the hardenability of steel.

Answer:

Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop.

True

Explanation:

It has been established that most technicians, instead of overhauling the defective power steering pumps, prefer to install rebuilt or revamped pumps or even new pumps when they could have overhauled the unit themselves.  Some are afraid that leakage could occur again.  They are not confident enough to do the overhauling in-house or some claim that they do not have the time and other tools to carry out the overhauling.  Acknowledgedly, overhauling a power steering pump is not a job for the novice.  They require experienced and skilled hands to do the hard work.

Answer:

Explanation:

Packet switching involves breaking a message into packets and sending them independently. Since the user only needs to transmit 10 percent of the time, the probability that a given (specific) user is transmitting = 10% = 0.1

The  probability that a user is not transmitting = 100% - 10% = 90% = 0.9

Therefore, the probability that a given (specific) user is transmitting, and the remaining users are not transmitting = 0.1 * 0.9 = 0.09

Answer:

the rate at which heat is added in the boiler = 59597.4 kW

the power required to operate the pumps = 122.57 kW

The net power produced by the cycle = 17925 kW.

The thermal efficiency = 30%.

Explanation:

The specific enthalpy of saturated liquid is equal to the enthalpy of the first point which is equal to 314 kJ/ kg.

The second enthalpy is calculated from the pump work. Therefore, the second enthalpy = first enthalpy point + specific volume of water [ the pressure of the boiler - the pressure of the condenser].

The second enthalpy = 314  + 0.00103 [ 6000 - 50 ] = 320.13 kJ/kg.

The specific enthalpy for the third point = 3300 kJ/kg.

Therefore, the rate at which heat is added in the boiler = 20 × [3300 - 320.13] = 59597.4 kW.

The rate at which heat is added in the boiler = 59597.4 kW.

Also, the power required to operate the pumps = 20 × 0.00103 [6000 - 50] = 122.57 kW.

The power produced by the turbine = 20 [ 300 - ( the fourth enthalpy value)].

The fourth enthalpy value = 3300 - 0.94 [ 3300 - 2340] = 2397.6 kJ/kg

Thus, the power produced by the turbine = 20 [ 300 - 2397.6] = 18048 kW.

The power produced by the turbine  =  18048 kW.

The net power produced =  18048  + 122.57 = 17925 kW.

The thermal efficiency = [net power produced] / [the rate at which heat is added in the boiler].

The thermal efficiency = 17925/ 59597.4 = 30%.

The theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5° respectively is; 3.54 g/cm³

The first thing we will do is to get the unit cell edge length from the given C - C distance.

From the structure of diamond;

Φ = ¹/₂ * bond angle

Φ = ¹/₂ * 109.5°

Φ = 54.75°

Thus;

θ = 90° - 54.75°

θ = 35.25°

Let the height from a point to the base of the cube of the structure be x. Thus;

x = a/4 = y sin θ

where a is unit cell edge length and y is C -C length. Thus;

a = 4y sin θ

a = 4 * (0.154 * 10⁻⁹) * sin 35.25°

a = 3.56 * 10⁻⁸ cm

The unit cell volume is;

V_c = a³

Thus; V_c = (3.56 * 10⁻⁸)³

V_c = 4.51 * 10⁻²³ cm³

Now, there are 8 equivalent atoms per unit cell and as such density is calculated from;

ρ = (n * A_c)/(V_c * N_a)

A_c is atomic weight of diamond = 12.01 g/mol

N_a is avogadro's number = 6.022 * 10²² atoms/g

Thus;

ρ = (8 * 12.01)/(4.51 * 10⁻²³ * 6.022 * 10²²)

ρ = 3.54 g/cm³

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
(Cop) = 4.490

The angular convergence and linear convergence experienced by the Chewela and Gulf Shores 7.5-minute topographic maps need to be computed using the Clarke spheroid of 1866 as the reference surface. The length of the parallel covered by the 7.5' on the southern boundary of each map is not the same due to the difference in latitude.

A) To compute the angular convergence, we need to determine the difference in latitude between the northern and southern edges of each map. The linear convergence can be calculated by multiplying the angular convergence by the distance between the northern and southern edges of the map. Using the given latitudes, the angular convergence and linear convergence for both Chewela and Gulf Shores can be computed using the Clarke spheroid of 1866 as the reference surface.

B) (a) The length of the parallel covered by the 7.5' on the southern boundary of each map is not the same because the maps are located at different latitudes. As latitude increases, the distance between lines of latitude decreases. Therefore, at a higher latitude like Chewela (48°15'00"N), the length covered by 7.5' is shorter compared to Gulf Shores (30°15'00"N).

(b) To achieve the same convergence angle in Chewela as in Gulf Shores, the topographic map for Chewela would have to be smaller. Since Chewela is at a higher latitude, it experiences a greater convergence angle than Gulf Shores. A smaller map would compensate for the larger convergence angle in Chewela.

(c) In the early 1800s, when surveying equipment had low precision, the effect of convergence would most likely be seen in field measurements in Alabama rather than Indiana. This is because Alabama (Gulf Shores) has a larger convergence angle than Indiana (Chewela). The convergence angle causes distortion in the field measurements, and the larger the convergence angle, the greater the distortion. Therefore, the effect of convergence would be more pronounced in Alabama due to its higher convergence angle compared to Indiana.

The cost per kilowatt-hour to operate the radio in this manner is $111.11/kWh.

To calculate the cost per kilowatt-hour (kWh), we first need to determine the total energy used by the radio. This can be calculated as follows:

Energy = Power x Time = Current x Voltage x Time

Power = Current x Voltage

= 50 mA x 9.0 V = 450 mW

Time = 300 hours = 300 x 60 minutes = 18000 minutes

Energy = 450 mW x 18000 minutes = 8.1 Wh

Next, we need to convert the energy from watt-hours to kilowatt-hours:

8.1 Wh ÷ 1000 = 0.0081 kWh

Finally, we divide the cost of the battery by the energy used to get the cost per kilowatt-hour:

cost per kWh = $0.90 ÷ 0.0081 kWh = $111.11/kWh

So the cost per kilowatt-hour to operate the radio in this manner is $111.11/kWh.

In this situation, both technicians could be correct. "Dog tracking" refers to a situation where the rear wheels of a vehicle do not track properly with the front wheels, resulting in the vehicle drifting slightly to one side or the other while driving straight.

This can be caused by several factors, including worn or misaligned suspension components, damaged tires, or an issue with the vehicle's frame.

Technician A suggests that a broken center bolt could be causing the issue. The center bolt is a component of the leaf spring suspension system, and if it were broken, it could cause the rear axle to shift out of alignment, resulting in dog tracking.

Technician B suggests that defective rear shock absorbers could be the cause. Shock absorbers help control the movement of the suspension system, and if they are worn or damaged, they may not be able to keep the rear axle in proper alignment, leading to dog tracking.

Ultimately, the best way to determine the cause of the issue would be to have the vehicle inspected by a qualified technician. They can check the suspension components, tires, and frame to identify any issues that may be contributing to the problem and recommend the appropriate repairs.

Answer:

a) the output voltage is 50 V

b)

- the average inductor current is 10 A

- the maximum inductor current is 13 A

- the maximum inductor current is 7 A

c) the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components is 4 A

Explanation:

Given the data in the question;

a) the output voltage

V₀ = V\(_s\)/( 1 - D )

given that; V\(_s\) = 20 V, D = 0.6

we substitute

V₀ = 20 / ( 1 - 0.6 )

V₀ = 20 / 0.4

V₀ = 50 V

Therefore, the output voltage is 50 V

b)

- the average inductor current

\(I_L\) = V\(_s\) / ( 1 - D )²R

given that R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6

we substitute

\(I_L\) = 20 / (( 1 - 0.6 )² × 12.5)

\(I_L\) = 20 / (( 0.4)² × 12.5)

\(I_L\) = 20 / ( 0.16 × 12.5 )

\(I_L\) = 20 / 2

\(I_L\) = 10 A

Therefore, the average inductor current is 10 A

- the maximum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] + [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmax\) = [20 / (( 1 - 0.6 )² × 12.5)] + [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmax\) = [20 / 2 ] + [ 60 / 20 ]    

\(I_{Lmax\) = 10 + 3

\(I_{Lmax\) = 13 A

Therefore, the maximum inductor current is 13 A

- The minimum inductor current

\(I_{Lmax\) = [V\(_s\) / ( 1 - D )²R] - [ V

given that, R = 12.5 Ω, V\(_s\) = 20 V, D = 0.6, L = 10 μH, T = 1/200 kHz = 5 hz

we substitute

\(I_{Lmin\) = [20 / (( 1 - 0.6 )² × 12.5)] - [ (20 × 0.6 × 5) / (2 × 10) ]

\(I_{Lmin\) = [20 / 2 ] -[ 60 / 20 ]    

\(I_{Lmin\) = 10 - 3

\(I_{Lmin\)  = 7 A

Therefore, the maximum inductor current is 7 A

c)  the output voltage ripple

ΔV₀/V₀ = D/RCf

given that; R = 12.5 Ω, C = 40 μF = 40 × 10⁻⁶ F, D = 0.6, f = 200 Khz = 2 × 10⁵ Hz

we substitute

ΔV₀/V₀ = 0.6 / (12.5 × (40 × 10⁻⁶) × (2 × 10⁵) )

ΔV₀/V₀ = 0.6 / 100

ΔV₀/V₀ = 0.006 or 0.6%V₀

Therefore, the output voltage ripple is 0.006 or 0.6%V₀

d) the average current in the diode under ideal components;

under ideal components; diode current = output current

hence the diode current will be;

\(I_D\) = V₀/R

as V₀ = 50 V and R = 12.5 Ω

we substitute

\(I_D\) = 50 / 12.5

\(I_D\) = 4 A

Therefore, the average current in the diode under ideal components is 4 A

Answer:

-2 and 6

Explanation:

Let "x" and "y" be 2 numbers.

The sum of the two numbers is 4. The mathematical expression is:

x + y = 4

y = 4 - x   [1]

The sum of their squares minus three times their product is 76. The mathematical expression is:

x² + y² - 3 x y = 76   [2]

If we substitute [1] in [2], we get:

x² + (4 - x)² - 3 x (4 - x) = 76

x² + 16 - 8 x + x² - 12 x + 3 x² = 76

5 x² - 20 x - 60 = 0

We apply the solving formula for second order equations and we get x₁ = 6 and x₂ = -2.

If we replace these x values in [1], we get:

y₁ = 4 - x₁ = 4 - 6 = -2

y₂ = 4 - x₂ = 4 - (-2) = 6

As a consequence, one of the numbers is 6 and the other is -2.
