1. A cylinder/piston contains 5 lbm water at 80 lbf /in.², 1000 F. The piston is restrained by a linear spring so when the system cools down due to heat transfer to the room at 70 F the water reaches a state of 80 F, x = 0.05. Calculate the total entropy generation due to this process.

2. A cylinder with a linear spring-loaded piston contains carbon dioxide gas at 300 lbf /in.2 with a volume of 2 ft³. The device is made of aluminum and has a mass of 8 lbm. Everything (Al and gas) is initially at 400 F. By heat transfer, the whole system cools to the ambient temperature of 77 F, at which points the gas pressure is 220 lbf /in.². Find the total entropy generation for the process.
