Consider the boundary layer next to the smooth hull of a ship. The ship is cruising at a speed of 45 ft/s in 60 o F fresh water. Assuming that the boundary layer on the ship hull develops the same as on a flat plate, determine: (a) The thickness of the boundary layer at a distance x = 100 ft downstream from the bow. (b) The shear stress, 0, adjacent to the hull at x = 100 ft.

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
