An insulated piston-cylinder arrangement contains water. Sixty percent of the total 15 kg of water are in the vapor phase. Steam at 1 MPa and 400°C is allowed to enter the cylinder from a supply line until all of the liquid in the cylinder is vaporized. The mass of the piston is such that it maintains a constant pressure of 200 kPa inside the cylinder. Assume the surroundings to be at 25°C and 100 kPa. Determine a) the amount of steam that enters in the cylinder and b) the entropy generation during this process.
