Question:

Water in a piston/cylinder is at 1 MPa, 500C. There are two stops, a lower one at which Vmin 1 m3 and an upper one at Vmax 3 m3. The piston is loaded with a mass and outside atmosphere such that it floats when the pressure is 500 kPa. This setup is now cooled to 100C by rejecting heat to the surroundings at 20C. Find the total entropy generated in the process.
