Consider a cubic furnace that is 0.2m long on each side. The two ends have diffuse, black surfaces that are maintained at 500 K (bottom surface) and 600 K (top surface). The side surfaces are also diffuse and black and at a temperature of 800 K. Set up the radiation network with 3 surfaces (surface 1-Bottom; surface 2-Top; surface 3-side surfaces and answer the following questions: Required:
What is the net heat transfer from the top surface (surface 2) to other surfaces?

answer:

me yeah

explanation:

answer:

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

//main function

int main()

{

  // variable

 int n;

 cout<<"enter a number:";

 // read the input

 cin>>n;

 // find the square root of the absolute value

 float square_root=sqrt(abs(n));

 // print the square_root

 cout<<"square root of "<<n<<" is: "<<square_root<<endl;

  return 0;

}

Explanation:

Read a number from user and assign it to "n".Then find its absolute value with abs() function.Then calculate the square root of the absolute value with sqrt() function.Print the square root of the number.

Output:

enter a number:-17

square root of -17 is: 4.12311
