Asimplified problem for a hydro plant involves a penstock of length 2500 ft, the velocity of the penstock is 6 ft/sec, the penstock area is 100 ft2, the surge tank area is proposed to be 2000 ft2, and the friction head loss in the pen stock is 3 ft. determine the approximate maximum pressure surge in the surge tank and time from beginning of flow until maximum surge if the gate valve is suddenly closed.

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
