Water flows through a horizontal pipe at a rate of 2.6 gal/s. The pipe consists of two sections of diameters 4 in. and 2 in. with a smooth reducing section. The pressure difference between the two pipe sections is measured by a mercury manometer. Neglecting frictional effects, determine the differential height of mercury between the two pipe sections. Take the densities of mercury and water as rhoHg = 847 lbm/ft3 and rhoW = 62.4 lbm/ft3. Horizontal bottle has nozzle at the right side. At the right side of nozzle, cylindrical horizontal shape is shown. The right arrow labelled as flow. The differential height of mercury between the two pipe sections is in.

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
