Transcribed Image Text:1. A fuel is represented with Cs Hg is burned with 42% excess air. If mass of fuel is 0.18 kg, find the
mass of air needed.
2. A fuel gas has the following volumetric analysis: CH, = 69% CHs = 32% Assume complete
combustion with 15% excess air at 101.325 Kpa, 21°C wet bulb and 27°C dry bulb. What is the
partial pressure of water vapor in Kpa?
3. There are 24 kg of flue gases formed per kg of fuel oil burned in the combustion of a fuel oil C12
H26. What is the excess air in percent?
4. Dodecane (C12H26) is burned at constant pressure with 153% excess air. What is the air-fuel for
this process?
5. A complete combustion of one kilogram of C1H32 resulted to 20 kilograms of products of
combustion. Calculate the percent excess air.
