If moist hydrogen containing 4% of water by volume is burnt completely in furnace with 32% excess air, calculate the Orsat analysis of the resulting flue gas. Ans. 6%O2,94%N2. 3. Calculate what should be the Orat analysis resulting from the complete combustion with 100% excess air of 4. An sutomobile engine is being operated with pure methyl alcohol, CH2OH, uaing 10% excess sir over that necessary for theoretical combustion, and securing substantislly complete combustion of the fuel. A sample of the exhaust gases is removed from the exhaust pipe and carefully analyzed in an Orsat. What analysis would you expect to get? 5. Pure formaldehyde gas, CH2O, is burnt completely in air, using 50% excess. (a) What should be the Orsat analysis of the combustion gas? (b) What should be the Orsat analysis of the combustion gas if, instead of using excess air, only enough were used to burn all the hydrogen to water, 25% of the carbon to CO2, snd the remaining 75% to CO, the combustion being so conducted that no oxygen gas whatever is left remaining in the combustion products
