Nitrogen (N2), at 300 K, 1 bar with a mass flow rate of 1 kg/s enters an insulated mixing chamber and mixes with carbon dioxide (CO2) entering as a separate stream at 500 K, 1 bar with a mass flow rate of 0.5 kg/s. The mixture exits at 1 bar. Assuming ideal gas behavior, for steady-state operation, determine (a) the molar analysis (i.e., the molar flow rate for each gas) of the exiting mixture, (b) the exit mixture temperature, and (c) the rate of entropy generation, in kW/k.
