Combustion gases passing through a 3 cm internal diameter circular pipe are used to vaporize waste water at atmospheric pressure. hot gases enter the pipe at 250 c at a mean velocity of 5 m/s, and leave at 150°c. if the average heat transfer coefficient is 40 w/m2-k and the inner surface temperature of the pipe is 110°c, determine the surface area of the pipe. (ρ = 0.7662 kg/m, cp=1023 j/kg-k) a. 0.012 m2 b. 0.035 m2 0.061 m2 c. d. 0.087 m2

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.

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
