Question

A fuel gas consisting of 94 mole % methane and 6 mole % nitrogen is burned with 35 % excess air in a continuous water heater. Both fuel gas and air enter dry at 298.15 k. Water is heated at a rate of 34 kg/s from 298.15 k to 368.15 k. The flue gas leaves the heater at 483.15 k. 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 surrounding.
