A sealed adiabatic piston/cylinder system is used to compress nitrogen gas (γ = 1.4, ¯m = 28.0 kg/kmol) from T1 = 300 K and p1 = 1.0 bar to a final pressure of p2 = 10 bar. Assume a calorically perfect gas over the temperature range of interest. (a) What is the minimum amount of specific work (wₘᵢₙ) required to achieve this compression? (b) The measured final temperature is T2 = 590 K. If the efficiency is defined as: η = wₘᵢₙ / wₐₜᵤₐₗ , what is the efficiency of this compression process?

answer:

it will water down the soup lol

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
