Question:

Water in a piston/cylinder, shown in Fig. P6.177, is at 1 MPa, 500◦C. There are two stops, a lower one at which V_min = 1 m³ and an upper one at V_max = 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 surrounding at 20◦C. Find the total entropy generated in the process.
