Methane is completely burned with 10% excess air. Methane and air enter the furnace at 25C and 100C, respectively. The combustion products leave the furnace at 400C. The flow rate of methane to the furnace is 100 mol/s. a) Perform a degree of freedom analysis of the process. b) Construct a complete inlet-outlet enthalpy table. c) Calculate the heat transferred (kW) from the furnace.
