A liquid fuel mixture that is 40% octane (C8H18) and 60% decane (C10H22) by mass is burned completely with 10% excess air at 25C, 1 atm, 80% relative humidity. (a) Determine the equivalent hydrocarbon composition, CaHb, of a fuel that would have the same carbonhydrogen ratio on a mass basis as the fuel mixture. (b) If the combustion products are cooled to 25C at apressure of 1 atm, determine the amount of water vapor thatcondenses, in kg per kg of fuel mixture.
