Abiodiesel mixture containing c16h34 and c11h10 was burned in an experimental diesel engine. the orsat analysis of the combustion gases reveal co2=7.38%, co=0.82%, o2=9.76% and the rest n2. determine: 1. the cetane number of the fuel 2. percent air used 3. the specific gravity of the fuel (given the specific gravities; c16h34=0.7751 c11h10=1.025) 4. the partial pressure of water if the dry combustion gases exits at 300c and 2 atm
