Answer: Problem Statement

Explanation:

When going about designing a new product or an improvement to an existing product, it is important to state the problem in a clear and concise way so that the designers know precisely what they are working towards.

This is where a Problem statement comes in. It states the problem in a concise manner and juxtaposes the current shortcomings of the current system against what the system should ideally be in such a way that even though the solution is clear, it is not so precise that it makes the designers narrow-minded.

The given assembly code in 8086 prompts the user to enter a string of maximum 20 characters, then reverses the input string using a stack, and finally outputs the reversed string on the console.

The assembly code follows these steps to achieve the desired functionality:

1.Prompting User Input:

The program starts by displaying a prompt message on the console, asking the user to enter a string. It waits for the user to input the string and press the enter key.

2.Storing Input String:

The program allocates memory to store the user's input string, assuming a maximum size of 20 characters. It copies the entered string to this allocated memory location.

3.Reversing the String using Stack:

To reverse the string, the program utilizes a stack data structure. It initializes a stack and iterates over each character in the input string. For each character, it pushes it onto the stack.

4.Outputting the Reversed String:

After the entire input string has been pushed onto the stack, the program starts popping the characters from the stack. Each popped character is printed on the console, resulting in the reversed string being displayed.

5.Program Termination:

Once the reversed string has been outputted, the program terminates.

Overall, this assembly code prompts the user for a string, reverses the string using a stack, and outputs the reversed string on the console. It demonstrates the manipulation of strings and the usage of stack data structure in 8086 assembly language.

Water: h = 35.53 W/m².k

Engine oil: h = 18.84 W/m².k

Mercury: h = 1.19 W/m².k

Explanation:

Assuming the steady state, one-dimensional heat flow, it is clear that the added to the fluid by tube heat will be equal to the heat transfer through convection outside the tube.

Therefore,

mCΔT = hAΔT

mC = hA

h = mC/A

where,

h = convection coefficient

m = mass flow rate =  0.01 kg/s

C = specific heat capacity of fluid

A = surface area of tube = 2πrL = 2π(0.0125 m)(15 m) = 1.178 m²

FOR WATER:

C = 4186 J/Kg.k

Therefore,

h = (0.01 kg/s)(4186 J/Kg.k)/(1.178 m²)

h = 35.53 W/m².k

FOR ENGINE OIL:

C = 2220 J/Kg.k

Therefore,

h = (0.01 kg/s)(2220 J/Kg.k)/(1.178 m²)

h = 18.84 W/m².k

FOR LIQUID MERCURY:

C = 140 J/Kg.k

Therefore,

h = (0.01 kg/s)(140 J/Kg.k)/(1.178 m²)

h = 1.19 W/m².k

Passing a plate of steel between rollers and decreasing its thickness by 50% causes a change in the average atomic distance in the vertical direction.

The process of reducing the thickness of a metal plate is known as rolling. During the rolling process, the metal atoms in the plate are displaced, resulting in a decrease in the average atomic distance in the vertical direction. This reduction in distance occurs because the metal atoms are being pushed closer together. As a result, the plate becomes denser and stronger. In conclusion, the rolling process causes a decrease in the average atomic distance in the vertical direction, resulting in a denser and stronger plate of steel.

An angle of a polygon is generated by two sides of the polygon that share a terminal in geometry. If a point within the angle is in the interior of a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle). Each vertex in a polygon has precisely one internal angle. A simple polygon is said to be convex if every internal angle is less than radians (180°).

The length of a 1 inch diameter 9 geothermal heat exchanger having water flow of above 2 US gpm to deliver 30 kW cooling capacity is 100.26 ft.

Given: Water flow, Q = 2 US gpm= 0.126 LPS

Length of the heat exchanger = ?

Diameter of the heat exchanger = 1 inch = 0.0833 ft

Ground temperature, Tg = 110 °F = 43.33 °C

Water inlet temperature, Tw1 = 80 °F = 26.67 °C

Effective heat transfer load, Qload = 30 kW

Load factor, Fc = 1

Coefficient of Performance, COP = 3.5S and

density, ρ = 100 lb/ft3

Now, Q = (6 + 2) × Qload= 8 × 30= 240 kW

We know that heat flow rate,

Q = (pi/4) x D^2 x L x ρ x Cp x dT/dt

where, pi= 3.14

D = 1 inch

= 0.0833 ft

ρ = 100 lb/ft3

Cp = 1 BTU/lb °FdT/dt

= (Tg - Tw1) / (COP x Fc)

= (43.33 - 26.67) / (3.5 x 1)

= 4.76 ft/hr

= 0.00132 ft/s (convert 4.76 ft/hr to ft/s)

Substituting all the values,

240,000 = (3.14/4) × (0.0833)^2 × L × 100 × 1 × 0.00132L

= 100.26 ft

Therefore, the length of a 1 inch diameter 9 geothermal heat exchanger having water flow of above 2 US gpm to deliver 30 kW cooling capacity is 100.26 ft.

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

To determine whether the flow in the 3-ft-diameter pipe will be laminar or turbulent, we can consider the Reynolds number. The Reynolds number (Re) is a dimensionless quantity that characterizes the flow regime based on the ratio of inertial forces to viscous forces.

The Reynolds number can be calculated using the following formula:

Re = (velocity × diameter) / viscosity

In this case, we are given the diameter of the pipe, but we don't have information about the velocity or the viscosity of the fluid. However, based on the context provided, which states that the pipe is completely filled with rainwater runoff from a parking lot, we can make an inference.

Rainwater runoff typically consists of water flowing at moderate velocities, and its viscosity is similar to that of water. In such cases, the flow is likely to be turbulent rather than laminar. Turbulent flow occurs at higher velocities and higher Reynolds numbers, where the fluid particles exhibit chaotic and random motion.

Considering the nature of rainwater runoff and assuming typical velocities, it is reasonable to expect that the flow in the 3-ft-diameter pipe would be turbulent rather than laminar. However, without specific information about the velocity and viscosity, it is not possible to provide a definitive answer.
