A rigid tank that contains N is connected to another rigid tank with O. The initial state of two tanks are indicated in the graph. The overall system is adiabatic to the environment. A valve connecting the two tanks is opened to allow the two gaes mix. find the final temperature and final pressure. Assuming constant specific heats evaluated at 25 C. find: (a) Final temperature (b) Final pressure (c) Entropy generation I+I Nitrogen 2 kg 25 C 550 kPa Oxygen 4 kg 25 C 150 kPa
