Question

1. Write out the combustion equation for methane (as used in a furnace) 2. What is the mole ratio of water vapor in the combustion products? If the products are at atmospheric pressure and the partial pressure ratio is equal to the molar ratio, then what is the partial pressure of the water vapor? 3. How many pounds of CO2 are produced from combusting one pound of methane? (Questions are continued on reverse side) 4. Knowing that the HHV of methane is 23,900 Btu/lbm, then how many pounds of CO2 are produced for every 100,000 Btu's being made available during combustion ( refer to HHV and question 3 above)
