A brayton cycle operates with a gas mixture of 78% nitrogen, 21% oxygen, and 1% carbon dioxide by volume. The gas mixture enters the isothermal compressor at 100 kPa and 298 K, and exits the compressor at 800 kPa. In the constant pressure heat exchanger, the gas mixture is heated to 1000 K. At the exit of the turbine, the gas mixture is at 400 K. Determine a) the work input to the compressor, b) the heat addition in the heat exchanger, c) the net work output, and d) the thermal efficiency of the system. Report all final answers in kJ/kg where applicable.
