Methane gas (CH4) at 25⁰C, 1 atm enters a steam generator operating at steady state and burns completely with 140% of theoretical air entering at 127⁰C, 1 atm. The products of combustion exit at 427⁰C, 1 atm. Kinetic energy and potential energy effects are negligible. If the rate of heat transfer from the furnace to the surroundings is 400 kW, determine the mass flow of methane, in kg/s
