A shell-and-tube heat exchanger is used for cooling 47 kg/s of a process stream flowing through the tubes from 160 C to 100°C. This heat exchanger has a total of 100 identical tubes, each with an inside diameter of 2.5 cm and negligible wall thickness. The average properties of the process stream are: rho 950 kg/m3, k = 0.50 w/m. K, cp-3.5 kJ/kg-K and μα 2.0 mPa-s. The coolant stream is water (cp- 4.18 kJ/kg K) at a flow rate of 66 kg/s and an inlet temperature of 10 C, which yields an average shell-side heat transfer coefficient of 4.0 kW/m2-K. Calculate the tube length if the heat exchanger has

(a) a 1-shell pass and a 1-tube pass and
(b) a 1-shell pass and 4-tube passes 1.

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
