Methane gas (CH₂) at 25 °C, 1 atm and a volumetric flow rate of 27 m³/h enters a heat-treating furnace operating at steady state. The methane burns completely with 140% of theoretical air entering at 127 °C, 1 atm. Products of combustion exit at 427 °C, 1 atm. Determine a. the volumetric flow rate of the air, in m³/h. b. the rate of heat transfer from the furnace, in kJ/h.
