A rigid, well-insulated tank contains air. A partition in the tank separates 12 ft³ of air at 14.7 lbf/in.², 40°F from 10 ft³ of air at 50 lbf/in.², 200°F, as illustrated in Fig. P6.46. The partition is removed and air from the two sides mix until a final equilibrium state is attained. The air can be modeled as an ideal gas, and kinetic and potential energy effects can be neglected. Determine the final temperature, in °F, and pressure, in lbf/in.² Calculate the amount of entropy produced, in Btu/°R. Air VL = 12 ft³ PL = 14.7 lbf/in.2 TL = 40°F - FIGURE P6.46 Air VR = 10 ft³ PR = 50 lbf/in.² TR = 200°F Air P2, T₂ A rigid, well-insulated tank contains air.
