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

#SPJ11

The statement that best describes the buckling mechanisms of an arch bridge is e. roll-through buckling is inhibited by the rigid frame action of the arches and the horizontal elements linking the two arches to each other.

Arch bridges are designed to support loads primarily through axial compression forces. However, they are also susceptible to different types of buckling under certain loading conditions. Roll-through buckling is one of the most critical types of buckling in arch bridges, where the arch rolls or twists laterally due to insufficient lateral bracing, resulting in instability and possible collapse.To inhibit roll-through buckling, arch bridges typically incorporate horizontal elements that link the two arches, creating a rigid frame action that can resist lateral forces. The angled suspenders also provide additional bracing to reduce the lateral displacement of the arches. In contrast, tension elements in the roadbed primarily resist the vertical forces that act on the bridge, such as the weight of the traffic and the weight of the bridge itself.In summary, the rigid frame action of the arches and the horizontal elements linking the two arches together are critical factors that inhibit roll-through buckling in an arch bridge.

Answer:

t₁ = 378.668 K

Explanation:

From the given information:

The heat dissipated (q) from the electrical device = \(10^4 W/m^2\)

The contact resistance between device and aluminium;

(R_{const} ) = 0.5× 10⁻⁴ m² K/W

Conductivity of aluminum (k)  = 238 \ W/mK

The thickness of aluminum plate (L) = 0.004 m

Convection coefficient (h) = 100 \ W/m^2 K

Surrounding temperature (t_2) = 278 \ k

According to Fourier's law of heat conduction.

\(q = \dfrac { t_1- t_2 }{R_{const} + \dfrac{L}{k} + \dfrac{1}{h} }\)

\(10^4 = \dfrac{t_1 - 278}{0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100} }\)

\(10^4 *( 0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100}) = t_1 - 278\)

\(100.668 = t_1 -278\)

t₁ = 378.668 K

The true power is obtained as 70.7 VA.

We define the power a the rate of doing work, we know that the power in a circuit is the product of the current and the voltage. In this case, we want to find the true power thus we have to involve the use of the phase shift in degrees.

Thus;

True power = PcosΦ

The paragraph focuses on explaining the Carnot Cycle, efficiency calculations, and the utilization of the efficiency equation in establishing the Kelvin temperature scale, while also discussing the energy source for the reversible adiabatic expansion in the absence of external heat supply.

The given paragraph discusses the Carnot Cycle and its thermodynamic concepts, efficiency calculations, and the utilization of the efficiency equation to establish the Kelvin temperature scale.

In the Carnot engine scenario described in part a), the efficiency of the engine can be calculated using the formula: efficiency = 1 - (Tc/Th), where Tc is the temperature of the cold reservoir (100°C) and Th is the temperature of the hot reservoir (300°C). The work output during each cycle can also be determined.

In part b), the temperature of the cold reservoir, Tc, at which the maximum efficiency is realized by the heat engine is explored. It is explained how Kelvin utilized a rearranged form of the efficiency equation to establish the Kelvin temperature scale: Tc = (1 - efficiency) * Th. The feasibility of the calculated temperature is discussed in relation to the engine's maximum efficiency.

In part c), it is noted that the temperature of the cold reservoir is determined during the reversible adiabatic expansion of the gas. The energy required for this expansion comes from the internal energy of the system itself, as there is no heat flow from the surroundings. The paragraph raises the question of the energy source for the expansion process without any external heat supply.

Answer:

Explanation:

Q1: Polling is a method of computer programming where a program repeatedly checks a specific location in memory for new data or an event to occur. This is often done in a loop, where the program continuously checks for new data or an event until it occurs.

Two disadvantages of polling are:

It can be inefficient, as the program must continuously check for new data or an event, which can consume a lot of processing power.

It can also lead to missed events or data, as the program may not be checking at the exact moment when the event or data occurs.

Q2: Memory interleaving is a technique used to improve the performance of computer memory systems by spreading data across multiple memory modules. This is done by interleaving the memory addresses so that data is spread evenly across all the modules, rather than being stored in one module.

This technique is used for performance enhancements because it allows for faster access to data by allowing multiple memory modules to be accessed at the same time, rather than having to access data from one module at a time. This results in faster data transfer rates and improved system performance. Additionally, memory interleaving can also improve the reliability of a system by spreading data across multiple memory modules, which reduces the risk of data loss in the event of a module failure.

Answer:

It should be within 10%

Explanation:

Cranking compression is simply the pressure that builds up inside cylinders when the valves are closed and the piston then moves up the bores to lead to compression of the mixture.

Cranking compression is normally measured in pounds per square inch (PSI).

When checking cranking compression, we should be looking for signs of replication between cylinders. It means that each cylinder should build pressure within about 5 percent of the others under the same number of starter revolutions. Thus, the variation between the highest and lowest readings should not be more than 10%

a) Probability that he goes to KARIM and orders Afghani Chicken:

P = 0.7 * 0.6 = 0.42

b) Two events are said to be independent when occurrence of one event does not affect the probability of the other event's occurrence. Here the person orders Afghani Chicken regardless of where he visits so the events are independent.

c)  P = 0.30 because he orders Afghani Chicken regardless of where he visits.

d)  Let A be the probability that he goes to KARIM:

P(A) = 0.7 * ( 1 - 0.6 ) = 0.28

Let A be the probability that he orders Afghani Chicken:

P(B) =  0.3 * 0.6 = 0.18

Let C be the probability that he goes to KARIM and orders Afghani chicken:

Java is a high-level programming language that has a concise syntax and is designed to be platform-independent. It is also a multi-paradigm programming language, which means that it supports a variety of programming styles, including object-oriented, imperative, and functional programming.

A do-while loop is a control flow statement that executes a block of code at least once before testing the condition. In other words, the loop will always execute once before checking the condition to see if it should execute again.

To implement a program that continues to bid until the user enters 'n' in Java, you can use a do-while loop. Here is an example:

import java.util.Scanner;

public class Main {  

public static void main(String[] args) {    

Scanner scanner = new Scanner(System.in);    

String response;    

do {      

System.out.println("Enter your bid:");      

int bid = scanner.nextInt();      

System.out.println("You bid " + bid);      

System.out.println("Do you want to continue bidding? (y/n)");      

response = scanner.next();    }

while (!response.equals("n"));    

System.out.println("Bidding is over.");  }}

This program prompts the user to enter a bid, displays the bid, and then prompts the user to enter 'y' to continue bidding or 'n' to stop bidding. If the user enters 'n', the program will exit the loop and display a message that bidding is over. In conclusion, you can use a do-while loop in Java to implement a program that continues to bid until the user enters 'n'.
