RP-1 is highly refined form of kerosene used for many first stage rocket engines. The average composition of it is indicated by CH1.9 a. What is the stoichiometric mixture ratio (MR) for RP-1 and oxygen? b. Now, you have a mixture of air and RP-1 with three times more air (in terms of moles) than is needed to burn all the fuel. How high is the final temperature? The heats of formation are given in the table below. In molar quantities, assume 1 mole of air is (O2+3.76N2). The reactants have a temperature of 25°C before combustion. You may use the average values of the specific heats for each constituent. C. Would the adiabatic flame temperature be lower or higher for a rocket engine that uses pure oxygen instead of air? Explain.

2. An automobile engine is being operated with pure methyl alcohol using 10% excess air over that necessary for theoretical combustion and securing substantially complete combustion of the fuel. A sample of the exhaust gases is removed from the exhaust pipe and carefully analyzed in the Orsat. What analysis would you Suspect to get? 3. Assume that in the operation of the engine in the previous problem, the air supply is reduced below in the theoretical value to the point such that 90% of the carbon in the fuel burns to CO2 and the remaining to CO. Assume also that under these conditions, the hydrogen in the gaseous combustion products is 40% of the CO in them, the oxygen being all consumed. Calculate the following: a. The Orsat analysis for the gases from the exhaust pipe b. The pounds of dry air required per pound fuel burnt c. The cubic feet of dry air that must be supplied to the engine per pound of fuel bumt, on the assumption that the barometer is normal and the air temperature is…
