A gaseous fuel containing methane and ethane is burned with excess air. The fuel enters the furnace at 25°C and 1 atm, and the air enters at 200°C and 1 atm. The stack gas leaves the furnace at 800°C and 1 atm and contains 5.32 mole% CO2, 1.60% CO, 7.32% O₂, 12.24% H₂O, and the balance ₂. 1. Calculate the molar percentages of methane and ethane in the fuel gas and the percentage excess air fed to the reactor. 2.

Q2: Gaseous CO2 is contained in a vertical piston-cylinder assembly by a piston of mass 50 kg and having a face area of 0.01 m2. The mass of the CO2 is 4 g. The CO2 initially occupies a volume of 0.005 m3 and has a specific internal energy of 657 kJ/kg. The atmosphere exerts a pressure of 100 kPa on the top of the piston. Heat transfer in the amount of 1.95 kJ occurs slowly from the CO2 to the surroundings, and the volume of the CO2 decreases to 0.0025 m3. Friction between the piston and the cylinder wall can be neglected. The local acceleration of gravity is 9.81 m/s2. For the CO2 determine (a) the pressure, in kPa, and (b) the final specific internal energy, in kJ/kg. Answer: 149.1 kPa, 262.8 kJ/kg
