The pressure of the gas inside the piston is 110 kPa and the spring is compressed by 0.1 m. The cylinder has a cross-sectional area of 1 m^2 and the piston mass is 1000 kg. Water (density= 1000 kg/m3) is slowly poured onto the piston to a depth is 5 m. The piston seal prevents any water from entering the gas-filled portion of the cylinder. During this process, the 10 kJ of work is provided to the paddle stirrer. Required:
Show that if that the piston-cylinder system contains 4 kg of ARGON and the piston is initially 5 m above the bottom of the cylinder, then heat removal of 1225.32 kJ is required to maintain a constant pressure for the process.

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.

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
