Mixed stream Ti = 300 K Q3.25 pts An ideal gas mixture consisting of 20% -300K O2 and 80% N2 (by mol) is separated into pure 02 P 1 atm and pure N2 streams. The gas mixture enters at 300 K, 1 atm, and pure gases leave at 300 K, 1 atm. Assuming steady-state, calculate the minimum work that is required to generate 1 kmol of pure 02. Assume that the heat transfer between the separator device and the surroundings...
