When a process is in a state of statistical control, all of the points on a control chart should fall within the control limits.

However, it is undesirable that all of the points should fall extremely near, or exactly on, the centerline of the control chart. Why?

it is undesirable that all of the points should fall extremely near, or exactly on, the centerline of the control chart Because:

  • It can make it difficult  to interpret patterns and draw conclusions in a run chart.
  • It can lead hinder the process, and make it unstable.
<h3>When a data point falls outside the control limits of a run chart ?</h3>

If a data point falls is said to outside the control limits, we can say that the process is said to be out of one's control and it is good that an investigation is done to ascertain and remove the cause or causes.

So, it is undesirable that all of the points should fall extremely near, or exactly on, the centerline of the control chart Because:

  • It can make it difficult  to interpret patterns and draw conclusions in a run chart.
  • It can lead hinder the process, and make it unstable.

A thick aluminum block initially at 26.5°C is subjected to constant heat flux of 4000 W/m2 by an electric resistance heater whos
Yanka [14]

Given Information:

Initial temperature of aluminum block = 26.5°C

Heat flux = 4000 w/m²

Time = 2112 seconds

Time = 30 minutes = 30*60 = 1800 seconds

Required Information:

Rise in surface temperature = ?

Answer:

Rise in surface temperature = 8.6 °C after 2112 seconds

Rise in surface temperature = 8 °C after 30 minutes

Explanation:

The surface temperature of the aluminum block is given by

T_{surface} = T_{initial} + \frac{q}{k} \sqrt{\frac{4\alpha t}{\pi} }

Where q is the heat flux supplied to aluminum block, k is the conductivity of pure aluminum and α is the diffusivity of pure aluminum.

After t = 2112 sec:

T_{surface} = 26.5 + \frac{4000}{237} \sqrt{\frac{4(9.71\times 10^{-5}) (2112)}{\pi} }\\\\T_{surface} = 26.5 + \frac{4000}{237} (0.51098)\\\\T_{surface} = 26.5 + 8.6\\\\T_{surface} = 35.1\\\\

The rise in the surface temperature is

Rise = 35.1 - 26.5 = 8.6 °C

Therefore, the surface temperature of the block will rise by 8.6 °C after 2112 seconds.

After t = 30 mins:

T_{surface} = 26.5 + \frac{4000}{237} \sqrt{\frac{4(9.71\times 10^{-5}) (1800)}{\pi} }\\\\T_{surface} = 26.5 + \frac{4000}{237} (0.4717)\\\\T_{surface} = 26.5 + 7.96\\\\T_{surface} = 34.5\\\\

The rise in the surface temperature is

Rise = 34.5 - 26.5 = 8 °C

Therefore, the surface temperature of the block will rise by 8 °C after 30 minutes.

Propane gas C3H8 enters a combustion chamber operating at steady state condition at 1 bar, 25ºC and is burned with 150% theoreti
GalinKa [24]

Answer:

see explaination

Explanation:

Balanced equation or stoichiometry equation means in a product after reaction there is no unburned carbon compound left or we can say the oxygen is sufficient to combine with all the carbon and hydrogen moleculs to form Carbon-dioxide and water respectively.

The dew point temperature of balanced equation will be 100°c because water vapour bis present in it and it will condense at 100°c at 1 bar pressure while the other products need much lower temperatures to liquify.

Answer:

See explaination and attachment for the program code and output

Explanation:

#include <iostream>

using namespace std;

int main()

{

char gender; //details for gender and checking

char ans;

do

{

cout<<"Gender (M or F): ";

cin>>gender;

switch(gender)

{

case 'M':

//cout<<"Male."<<endl;

break;

case 'F':

//cout<<"Female."<<endl;

break;

default:

cout<<"Wrong Gender. Please enter again (M or F): ";

cin>>gender;

}

int Weight,Height,Age; //declaration of variables

double bmr;

cout<<"Weight: ";

cin>>Weight;

cout<<"Height (in inches): ";

cin>>Height;

cout<<"Age: ";

cin>>Age;

//bmr calculations for male and female

if (gender = 'M')

{

bmr = 66 + (6.3 * Weight) + (12.9 * Height) - (6.8 * Age);

cout<<"He needs "<<bmr<<" to maintain his weight."<<endl;

cout<<"He needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;

}

else if (gender = 'F')

{

bmr = 655 + (4.3 * Weight) + (4.7 * Height) - (4.7 *Age);

cout<<"She needs "<<bmr<<" to maintain her weight"<<endl;

cout<<"She needs to eat "<<(bmr/230)<< " candy bars in one day."<<endl;

}

cout<< "Do you want to do another one>continue (Y/N): ";

cin >> ans;

The magic square is an arrangement of numbers in a square grid in such a way that the sum of the numbers in each row, and in eac
Yuki888 [10]

Answer:

See the explanation for the answer;

Explanation:

Matlab code is as given below

-------------------------------------------------------------------------------------Start of code

% Program to create a magic square and verify it

clc

M= magic(5)

% To find sum of elements of each row

r1= sum(M(1,:))      % Sum of row 1

r2= sum(M(2,:))      % Sum of row 2

r3= sum(M(3,:))      % Sum of row 3

r4= sum(M(4,:))      % Sum of row 4

r5= sum(M(5,:))      % Sum of row 5

% To find sum of each coloumn

c1= sum(M(:,1))      % Sum of coloumn 1

c2= sum(M(:,2))      % Sum of coloumn 2

c2= sum(M(:,3))      % Sum of coloumn 3

c2= sum(M(:,4))      % Sum of coloumn 4

c2= sum(M(:,5))      % Sum of coloumn 5

% To find sum of diagonal

d1= sum(diag(M))               % Sum of principal diagonal elements

d2= sum(diag(fliplr(M)))      

-------------------------------------------------------------------------------End of code

Following results are obtained when executed.

M =

   17    24     1     8    15

   23     5     7    14    16
