(50 pts) consider a 25-mm-diameter and 15-m-long smooth tube that is used for heating water. the tube wall is heated electrically to provide a constant surface heat flux alone the entire tube. water enters the tube at 50°c and exist at 150°c. if the mass flow rate is maintained at 0.01 kg/s, determine:
a. the surface heat flux
b. the convection heat transfer coefficient at the tube outlet

energy can cross the boundaries of a closed system in the form of heat and mass

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
