An equimolar mixture of two ideal gases (A, B) expands isentropically in a nozzle. The gas mixture enters the nozzle at 300 kPa, 400 K and exits at 100 kPa. Assuming the mixture to be an ideal gas, the exit temperature of the gas mixture (in K) is _________. Molar mass (kg/kmol) Cp (kJ/kg-K) Gas A 28.013 1.04 Gas B 2.016 14.21
Answer: 286 to 297
