A two-stage compressor is used to compress 15 moles of carbon dioxide gas at 300 K and 100 kPa. The first stage compresses the gas to 400 kPa and the second stage from 400 kPa to 2000 kPa. Assume that first compressor is well insulated and has an isentropic efficiency of 80% but the second compressor is well insulated and well lubricated. There is no cooling between the compressors. Calculate the power required (to nearest kW) for each stage compressor and the entropy generated (to nearest W/K) by each compressor. Assume that carbon dioxide behaves as an ideal gas and its op' (J/mol-K)-25+0.2T

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
