Question 2 6 pts The actual combustion equation of octane in air was determined to be C8H18 + 1402 + 52.64N26CO2 + 2CO + 9H₂O + 2.502 + 52.64N2 If 14.37 kg of carbon dioxide was produced, how much octane was burned? Express your answer in kg. Question 1 6 pts C4H10 is burned at an actual AFR of 16.5 kg fuel/kg air. What percent excess air or deficient air is this AFR? Express your answer in percent, positive if excess air or negative if deficient air. Question 3 6 pts The combustion of ethylene (C₂H4) in air gave the following balanced actual combustion reaction: C₂H4 +a (O2 + 3.76 N₂) 1.8 CO₂ + 0.2 CO + 2H₂O + (a - 2.9) O2 + 3.76a N₂ If the number of moles of O₂ supplied is a = 5.57, what is the absolute humidity of the products? Express your answer in kg v/kg dg. Question 4 5 pts A closed vessel contains moist air at 42°C and 1.36 bar. If the mole fraction of the water vapor in the air is 3.5%, what is the humidity ratio of the moist air? Express your answer in kg v/kg da.
