Aleading manufacturer of household appliances is proposing a self cleaning oven design that involves use of a composite window separating the oven cavity from the room air. the composite is to consist of two high temperature plastics (a and b) of thicknesses xa = 2 xb and thermal conductivities ka = 0.15 w/m. k and kb = 0.08 w/m. k. during the self cleaning process, the oven air temperature is 400°c while the room air temperature is 25°c. the inside and outside convection coefficients are approx. 25 w/m².k. what is the minimum window thickness, x =xa + xb needed to ensure that the outside surface temperature the window remains less than 50°c for safety reasons?

jomamais ay

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
