Octane (C8H18) Is combusted with excess air. The product gas composition is partially known. The dry gas compositions of octane and carbon dioxide are: Octane mole fraction - 0.0062
Carbon dioxide mole fraction - 0.0455
What is the percent excess air fed to the combustor? Assume combustion is complete and use a basis of 100 mol/h of the dry gas (stream 4 below) for your calculations. Note the reaction below is not balanced. Report answer to three sig figs.

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
