A rigid tank of volume 0.63 m3 initially has some air inside at 0.5 bar and 300 K. A hole develops in the wall, and air from the surroundings at 1 bar, 300 K flows in until the pressure in the tank reaches 1 bar. Heat transfer between the contents of the tank and the surroundings is negligible. Determine the final temperature in the tank, in K. What is the entropy generation of the process? (Please treat the air as ideal gas with cp=1.001 kJ/kg?K and cv=0.714 kJ/kg?K)

Nitrogen gas is contained in a rigid 1-m3 tank, initially at 5 bar, 300 K. Heat transfer to the contents of the tank occurs until the temperature has increased to 400 K. During the process, a pressure-relief valve allows nitrogen to escape, maintaining constant pressure in the tank. Neglecting kinetic and potential energy effects, and using the ideal gas model with constant specific heats evaluated at 350 K, determine (a) the mass of nitrogen that escapes, in kg, and (b)...
