A fuel gas consisting 0f 94 mol % methane and 6 mol % nitrogen is burned with 35% excess air in a continuous water heater. Both fuel gas and air enter dry at 77(F). Water is heated at a rate of 75(lbm/s) from 77 F to 203 F. The flue gases leave the heater at 410 F. Of the entering methane, 70% burns to carbon dioxide and 30% burns to carbon monoxide. What volumetric flow rate of fuel gas is required if there are no heat losses to the surroundings?
