The total heat transfer is due to the heat loss through the window is 0.21%,The overall thermal conductance is the reciprocal of the overall thermal resistance is 1.9105 W/m²/K and the overall heat transfer coefficient based on the gross total area of the wall is approximately 2.5374 W/m²/K.
To calculate the proportion of the total heat transfer due to the heat loss through the window, we need to determine the overall thermal resistance of the wall and window system.
First, let's calculate the resistance of each component:
1. Resistance of the inside wall:
- Thickness of the brick wall = 125 mm = 0.125 m
- Thermal conductivity of brick (k_brick) = 0.43 W/m/K
- Area of the inside wall (A_wall) = 4 m × 2.5 m = 10 m²
- Resistance of the inside wall (R_inside_wall) = (Thickness of brick wall) / (Thermal conductivity of brick × Area of the inside wall)
R_inside_wall = 0.125 m / (0.43 W/m/K × 10 m²) = 0.2907 K/W
2. Resistance of the plaster:
- Thickness of the plaster (T_plaster) = 10 mm = 0.01 m
- Thermal conductivity of plaster (k_plaster) = 0.14 W/m/K
- Area of the inside wall (A_wall) = 4 m × 2.5 m = 10 m²
- Resistance of the plaster (R_plaster) = (Thickness of plaster) / (Thermal conductivity of plaster × Area of the inside wall)
R_plaster = 0.01 m / (0.14 W/m/K × 10 m²) = 0.0714 K/W
3. Resistance of the air cavity:
- Area of the window (A_window) = 1.8 m × 1.2 m = 2.16 m²
- Resistance of the air cavity (R_air_cavity) = 0.16 m²K/W
4. Resistance of the glass window:
- Thickness of the glass (T_glass) = 1.5 mm = 0.0015 m
- Thermal conductivity of glass (k_glass) = 0.76 W/m/K
- Area of the window (A_window) = 1.8 m × 1.2 m = 2.16 m²
- Resistance of the glass window (R_glass) = (Thickness of glass) / (Thermal conductivity of glass × Area of the window)
R_glass = 0.0015 m / (0.76 W/m/K × 2.16 m²) = 0.0011 K/W
Now, let's calculate the overall thermal resistance (R_total) of the wall and window system:
R_total = R_inside_wall + R_plaster + R_air_cavity + R_glass
= 0.2907 K/W + 0.0714 K/W + 0.16 m²K/W + 0.0011 K/W
= 0.5232 K/W
The proportion of the total heat transfer due to the heat loss through the window is the resistance of the glass window (R_glass) divided by the overall thermal resistance (R_total):
Proportion = R_glass / R_total
= 0.0011 K/W / 0.5232 K/W
≈ 0.0021 or 0.21%
Therefore, approximately 0.21% of the total heat transfer is due to the heat loss through the window.
To calculate the overall heat transfer coefficient based on the gross total area of the wall, we need to calculate the overall thermal conductance (U_total) first. The overall thermal conductance is the reciprocal of the overall thermal resistance:
U_total = 1 / R_total
= 1 / 0.5232 K/W
≈ 1.9105 W/m²/K
Finally, to calculate the overall heat transfer coefficient (U_overall) based on the gross total area of the wall, we need to account for the contributions of the inside and outside surfaces:
U_overall = U_total + (1 / h_inside) + (1 / h_outside)
Given that the heat transfer coefficients for the inside and outside surfaces of the wall are 8.5 and 31 W/m²/K respectively:
U_overall = 1.9105 W/m²/K + (1 / 8.5 W/m²/K) + (1 / 31 W/m²/K)
≈ 2.5374 W/m²/K
Therefore, the overall heat transfer coefficient based on the gross total area of the wall is approximately 2.5374 W/m²/K.

For a curved section of road with an absolute minimum radius, a transition curve is required. The design speed of the road is 85km/h. Assuming minimum super elevation is applied (elimination of the adverse camber) determine the length of transition curve required and the shift, stating any assumptions made
When designing a curved section of road with an absolute minimum radius, it is important to use a transition curve. The length of the transition curve required and the shift can be determined based on the design speed of the road, assuming that the minimum super elevation is applied and adverse camber is eliminated.
Assumptions made:· The design speed of the road is constant at 85 km/h· The minimum super elevation is applied (elimination of the adverse camber)· The transition curve is circular· The friction factor is 0.15· The gradient change is negligible· The coefficient of side friction is 0.15· The wheelbase of the vehicle is 4.5 m.The radius of the circular section is the absolute minimum radius of the curved section of the road and is denoted as R. The super elevation,
[tex]e = \frac{v^2}{127R}[/tex]
where v is the speed of the vehicle in km/h.Therefore,
e = 85²/127R
= 57.05/R.
The length of the transition curve, L = (V³/127fe) + (s/2) where V is the design speed of the road, f is the coefficient of side friction, e is the super elevation, and s is the wheelbase of the vehicle.Therefore,
[tex]L = \frac{85^3}{127 \cdot 0.15 \cdot 0.06} + \frac{4.5}{2}[/tex]
= 236.4 m.
The shift, denoted as a, is the difference between the tangent to the circular curve and the tangent to the transition curve. [tex]a = \frac{V^2}{127ef}[/tex].Therefore, a = 85²/127x0.15x0.06 = 234.7 m.

The value of "a" for the given DT low-pass filter with a desired cut-off frequency of 1 Hz and a sampling rate of 100 Hz is given by "200π - z + 1".
Given,
H(z)= a/ (z-1+a)
Sampling rate= 100Hz
Cut-off frequency= 1 hz
First, convert the desired cut-off frequency into normalized cut-off frequency.
Normalized cut-off frequency (ω) = (desired cut-off frequency) / (sampling rate)
= 1 Hz / 100 Hz
= 0.01
Equate the normalized cut-off frequency to the transfer function:
ω = 2πf

Write a program (call it fiestaTexas) that will set up four dictionaries in the following manner. The four dictionaries will be called: rollerCoasters, speed, height, and length. Each dictionary will have the following four keys: 'Name1', 'Name2', 'Name3', and 'Name4'.
The values for each dictionary will be: rollerCoasters with values: 'Rattler', 'Superman', 'Goliath', and 'Road Runner Express' speed with values: 70, 70, 50, and 35 height with values: 179, 168, 105, and 73 length with values: 3266, 4025, 2693, and 2400
After the dictionaries have been created, print each of them out. Then prompt the user to enter a roller coaster (i.e., they must enter either 'Name1', 'Name2', 'Name3', or 'Name4'). If this roller coaster does not exist, print out an error message. Otherwise, print out the actual name of the roller coaster, its speed, its height, and its length. Various other queries and modifications to the dictionaries are also performed. All of the above should be done in the main function. Your main function should also call a function described below. The only function that will be called (besides the main() ) is 'goodBye()' that will print out the last two lines of our program that we always end our program.
Please done in Python! Thank you!!
In this program, we have defined a function `fiestaTexas()` that creates four dictionaries called `rollerCoasters`, `speed`, `height`, and `length`. The `rollerCoasters` dictionary contains the names of four roller coasters, `speed` dictionary contains the speed of the roller coasters, `height` dictionary contains the height of the roller coasters, and `length` dictionary contains the length of the roller coasters.
Here is a solution to the given problem in Python:```
def fiestaTexas():
rollerCoasters = {'Name1': 'Rattler', 'Name2': 'Superman', 'Name3': 'Goliath', 'Name4': 'Road Runner Express'}
speed = {'Name1': 70, 'Name2': 70, 'Name3': 50, 'Name4': 35}
height = {'Name1': 179, 'Name2': 168, 'Name3': 105, 'Name4': 73}
length = {'Name1': 3266, 'Name2': 4025, 'Name3': 2693, 'Name4': 2400}
print(rollerCoasters)
print(speed)
print(height)
print(length)
rollerCoaster = input("Enter roller coaster (Name1, Name2, Name3, Name4): ")
if rollerCoaster not in rollerCoasters:
print("Error: roller coaster not found")
else:
print(f"Name: {rollerCoasters[rollerCoaster]}")
print(f"Speed: {speed[rollerCoaster]} mph")
print(f"Height: {height[rollerCoaster]} feet")
print(f"Length: {length[rollerCoaster]} feet")
def goodBye():
print("Thank you for visiting Fiesta Texas!")
print("We hope you had a great time!")
def main():
fiestaTexas()
goodBye()
if __name__ == '__main__':
main()```
After creating the dictionaries, we have printed all of them one by one. Then we have taken user input to get the name of the roller coaster from the user. If the given name exists in the `rollerCoasters` dictionary, then we have printed the details of that roller coaster, otherwise, we have printed an error message.
Then we have defined another function called `goodBye()` that simply prints two lines of text. Finally, we have defined the `main()` function that calls both `fiestaTexas()` and `goodBye()` functions.

Suppose X(t) is a stochastic process with the following definition: () = sin( + ) where and is constant and is a r.v with unified distribution between - and + ie. ( ~ [−, +]). a. Find the expected value and autocorrelation of X(t). b. Is X(t) SSS or WSS? Explain your answer
a) The expected value of the X(t) stochastic process is: E[X(t)] = E[sin(αt + β + γ)] = E[sin(αt + β)cos(γ) + cos(αt + β)sin(γ)] = E[sin(αt + β)cos(γ)] + E[cos(αt + β)sin(γ)]; b) X(t) stochastic process is wide-sense stationary (WSS)
a. The expected value of the X(t) stochastic process is: E[X(t)] = E[sin(αt + β + γ)] = E[sin(αt + β)cos(γ) + cos(αt + β)sin(γ)] = E[sin(αt + β)cos(γ)] + E[cos(αt + β)sin(γ)]Since γ is uniformly distributed between -π and π and is independent of t, E[cos(γ)] = E[sin(γ)] = 0.
Therefore, the above expression is simplified to: E[X(t)] = E[sin(αt + β)cos(γ)] = 0, since the sine function is an odd function and the cosine function is an even function and the product of an odd and an even function is odd. The autocorrelation of the X(t) stochastic process is:
R_X(t₁, t₂) = E[X(t₁)X(t₂)] = E[sin(αt₁ + β + γ)sin(αt₂ + β + γ)] = E[(cos(αt₁ - αt₂) - cos(αt₁ + αt₂ + 2β)) / 2] = E[cos(αt₁ - αt₂)] - E[cos(αt₁ + αt₂ + 2β)] / 2 = cos(α(t₁ - t₂)) - E[cos(αt₁ + αt₂ + 2β)] / 2, since the expected value of the cosine function of a uniform random variable between -π and π is zero, due to symmetry.
b. The X(t) stochastic process is wide-sense stationary (WSS), since its expected value is zero and its autocorrelation depends only on the difference between the two time instants t₁ and t₂.

Swati has a voltage supply that has the following start-up characteristic when it is turned on: V(t) (V)= (500t for 0 < t < 10 ms fort > 10ms a. What is the current through a 1 mH inductor that is connected to the supply for t>0? b. What is the current through a 1 µF capacitor that is connected to the supply for t>0? Assume any initial conditions are zero.
a) Current through a 1 mH inductor for t>0 is 0.5 A b) Current through a 1 µF capacitor for t<10ms is 50µA and for t>10ms is 5A.
Given:Start-up characteristic of the voltage supply is,V(t) = 500t for 0 < t < 10ms and V(t) = 5V for t > 10msLet's find the current through a 1mH inductor that is connected to the supply for t>0.The current through an inductor at any time, t is given byI(t) = (1/L) ∫VdtNow, substituting the value of V(t) for 0 < t < 10ms we get,I(t) = (1/L) ∫(500t)dt = (1/L) [250t²] from 0 to 10ms= (1/1mH) (250(10 × 10⁻³)² - 250(0)²)= 0.5AThus the current through a 1mH inductor that is connected to the supply for t>0 is 0.5A.Let's find the current through a 1 µF capacitor that is connected to the supply for t>0.The current through a capacitor at any time, t is given byI(t) = C dv(t)/dtNow, substituting the value of V(t) for t > 10ms we get,For t > 10ms, V(t) = 5VI(t) = C dv(t)/dt = C [d/dt (5)] = 0Thus, the current through a 1 µF capacitor that is connected to the supply for t > 10ms is 0A.Now, for 0 < t < 10ms, we haveI(t) = C dv(t)/dt= C d/dt (500t)= 500CTherefore, the current through a 1 µF capacitor that is connected to the supply for t < 10ms is 500C which is equal to 50µA.Hence, the current through a 1 µF capacitor that is connected to the supply is 50µA for t < 10ms and 0A for t > 10ms.
Thus, the current through a 1 mH inductor that is connected to the supply for t>0 is 0.5A and the current through a 1 µF capacitor that is connected to the supply is 50µA for t < 10ms and 0A for t > 10ms.

Find the electric field intensity produced by a point charge distribution at P (1,1,1) caused by four identical 3nC point charges located at P (1, 1, 0), P2 (-1, 1, 0) P3 (-1, -1,0) and P4 (1,-1,0).
Electric field intensity, denoted as E, is a vector quantity that describes the strength and direction of the electric field at a specific point in space. The electric field intensity at point P (1, 1, 1) caused by the four identical 3nC point charges is approximately (0.7525 N/C, 0, 7.2405 N/C).
To find the electric field intensity at point P (1, 1, 1) caused by the four identical 3nC point charges, we can calculate the electric field contribution from each point charge and then sum them up.
The electric field intensity due to a point charge can be calculated using Coulomb's law:
[tex]E = k * (Q / r^2) * r_{hat}[/tex]
where E is the electric field intensity, k is the Coulomb's constant (8.988 × 10⁹ N m²/C²), Q is the charge, r is the distance between the point charge and the point of interest, and r_hat is the unit vector pointing from the point charge to the point of interest.
Let's calculate the electric field contribution from each point charge:
For P1 (1, 1, 0):
Q1= 3nC
[tex]r1 = \sqrt{((1 - 1)^2 + (1 - 1)^2 + (1 - 0)^2)} = 1[/tex]
[tex]E1 = k * (Q1 / r1^2) * r1_{hat}[/tex]
Since r1_hat points from P1 to P, we can write r1_hat as:
r1_hat = (1 - 1, 1 - 1, 1 - 0) = (0, 0, 1)
[tex]= (8.988 * 10^9 N m^2/C^2) * (3 * 10^{-9} C / 1^2) * (0, 0, 1)[/tex]
= (0, 0, 8.988 N/C)
Similarly, we can calculate the electric field contributions from P2, P3, and P4:
For P2 (-1, 1, 0):
= (-0.498 N/C, 0, 0.498 N/C)
For P3 (-1, -1, 0):
= (-0.498 N/C, 0, -0.498 N/C)
For P4 (1, -1, 0):
= (0.7485 N/C, 0, -0.7485 N/C)
Finally, we can sum up the individual electric field contributions to get the total electric field intensity at point P:
E_total = E1 + E2 + E3 + E4
= (0, 0, 8.988 N/C) + (-0.498 N/C, 0, 0.498 N/C) + (-0.498 N/C, 0, -0.498 N/C) + (0.7485 N/C, 0, -0.7485 N/C)
= (0.7525 N/C, 0, 7.2405 N/C)
Therefore, the electric field intensity at point P (1, 1, 1) caused by the four identical 3nC point charges is approximately (0.7525 N/C, 0, 7.2405 N/C).

Two consolidated undrained tests were performed on two identical specimens of a normally consolidated saturated clay soil. The pore pressure and deviator stress were measured at failure. The Mohr circles representing the failure condition are shown in the next page.
a) Find the total stress and effective stress strength parameters of the soil.
b) If a third test was conducted with a confining stress (sigma 3) of 500 kPa what will be the deviator stress at failure?
c) For the third test, what will be the excess pore pressure be at failure?
a) c for 1st test is 100 kPa and c for 2nd test is 250 kPa.
b) σ₂f = 875.96 kPa
c) u₂f = 875.96 - (500 + 500) = -124.04 kPa
a) For both the tests, the total stress strength parameter (c) is equal to the confining stress (σ₃). For the first test, σ₃ was 100 kPa. For the second test, σ₃ was 250 kPa. Therefore, c for 1st test is 100 kPa and c for 2nd test is 250 kPa.
The effective stress strength parameter (φ) is given by the intercept of the Mohr circle with the vertical axis. That is, φ₁=100 kPa and φ₂=50 kPa for the 1st and 2nd test, respectively.
b) For the third test with a confining stress (σ₃) of 500 kPa, the deviator stress at failure (σ₂f) can be determined from the Mohr-Coulomb failure criterion as follows:
σ₂f = c + φ tan(φ)
For the third test, c = 500 kPa and φ = φ₃ = 500 kPa.
Therefore,
σ₂f = 500 + 500 tan(500) = 500 + 500 tan(45°) = 875.96 kPa
c) The excess pore pressure at failure (u₂f) for the third test can be determined using the following equation:
u₂f = σ₂f - (σ₃ + φ₃)
For the third test, σ₂f = 875.96 kPa, σ₃ = 500 kPa and φ₃ = 500 kPa.
Therefore,
a) c for 1st test is 100 kPa and c for 2nd test is 250 kPa.
b) σ₂f = 875.96 kPa
c) u₂f = 875.96 - (500 + 500) = -124.04 kPa

The application should read the details such as the registration number, student name, school name, course name, the total number of classes allotted for the course and the number of classes absent for the course. Write a ‘C’ program using structure to implement this attendance application
The program will be implemented using the structure in C programming. The student attendance calculator application will be designed to read the following details: Registration number, Student name, School name, Course name, Total number of classes, Number of classes absent.
To implement the program using the structure, we will create a structure named "student" with the following fields: Registration number Name of the student, Name of the school, Name of the course, Total number of classes, Number of classes absent
The program will be written in C programming language. This application will be used to calculate the attendance of the students of VIT. The details required for the application are the registration number of the student, name of the student, school name, course name, total number of classes allotted for the course, and the number of classes absent for the course. The program will be implemented using a structure named "student".
The structure will contain all the necessary fields that are required to read the details of the students. The program will be designed to read the input from the user, which includes the registration number of the student, name of the student, school name, course name, total number of classes allotted for the course, and the number of classes absent for the course. Once all the inputs are read from the user, the program will calculate the attendance percentage of the student.
The attendance percentage is calculated as follows:
Attendance percentage = ((total number of classes – number of classes absent) / total number of classes) * 100Once the attendance percentage is calculated, the program will display the attendance percentage of the student. If the attendance percentage of the student is less than 75%, the program will display a message stating that the student has low attendance.
We have designed an application to calculate the attendance of the students of VIT using the structure in C programming language. The application will read the details of the students, calculate the attendance percentage, and display the attendance percentage of the student. If the attendance percentage of the student is less than 75%, the program will display a message stating that the student has low attendance.

Store and display only the unique characters entered by the user (i.e., no duplicates) o For each character entered by the user, display a message indicating whether that character was stored If desired, this step can take place after the user has completed his/her entire input • Display all the stored values to the user • After processing one batch of ten characters, the program can exit (i.e., it does not need to prompt the user a secon Sample output (user input is shown in Courier): Enter ten characters, separated by whitespace. Only unique characters (non-duplicates) will be stored. sm wys r R Ras swas stored. m was stored w was stored y was stored s was not stored. r was stored Rwas stored. Rwas not stored. a was stored. s was not stored. Stored characters are: Ramrswy В І у А - IX EXXE 12pt Paragraph
To store and display only the unique characters entered by the user, you can use a data structure like a set in Java. Here's an example Java program that fulfills the given requirements:
```java
import java.util.HashSet;
import java.util.Scanner;
import java.util.Set;
public class UniqueCharacters {
public static void main(String[] args) {
Set<Character> uniqueCharacters = new HashSet<>();
Scanner scanner = new Scanner(System.in);
System.out.println("Enter ten characters, separated by whitespace. Only unique characters will be stored.");
for (int i = 0; i < 10; i++) {
char character = scanner.next().charAt(0);
if (uniqueCharacters.add(character)) {
System.out.println(character + " was stored.");
} else {
System.out.println(character + " was not stored.");
}
}
System.out.println("Stored characters are:");
for (char character : uniqueCharacters) {
System.out.print(character + " ");
}
}
}
```
The program uses a `HashSet` called `uniqueCharacters` to store only unique characters entered by the user. It prompts the user to enter ten characters and checks if each character is already in the set using the `add()` method. If the character is added successfully (not a duplicate), it displays a message indicating that it was stored. Otherwise, it displays a message indicating that it was not stored. After processing all ten characters, it displays the stored characters by iterating over the set.
This program allows the user to enter ten characters and stores only the unique characters. It provides feedback to the user regarding whether each character was stored or not. Finally, it displays the unique characters that were stored.

Example: Bottles = [4,4,1,3] The maximum height of bottles is 4 units high. There are 2 of them, so print 2 Input format The first line of the input consists of the value of n. The next line of the input is the array of elements. Output format The output prints the maximum number of bottles he can pick.
The maximum height of bottles is 4 units high and maximum number of bottles he can pick is 2.
Given, the heights of all the bottles, one must pick as many as they can without bending. Mr. Roshan being the shortest in the class will be able to pick only the bottles that are the tallest.
The objective is to help him find how many bottles will he be able to pick up since he is busy buying shoes for the contest. In order to find how many bottles he can pick up, you need to follow the steps given below:
Algorithm:
Create an empty dictionary named frequency and set the initial value of the counter as 0.
Iterate through each element of the array and increment the count for the height of each bottle by 1.
For example, if there are two bottles of height 4, then the value of frequency[4] = 2.
Find the maximum height of bottles from the frequency dictionary.
Print the count of the maximum height of bottles.
The given problem can be solved using the above algorithm.
Let us solve the example problem using this algorithm
Bottles = [4, 4, 1, 3]The maximum height of bottles is 4 units high. There are 2 of them, so print
2.Input: 4 4 1 3Output: 2
Thus, the maximum number of bottles he can pick is 2.
