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?
Calculate the total volume of gas (at 120 and 754 ) produced by the complete decomposition of 1.51 of ammonium nitrate.
