Problem 5 Liquid gasoline, C8H18, at 25C is burned steadily and completely with 150% theoretical air at 15C and 1atm. a) Determine the air-fuel ratio and the highest possible temperature that can be obtained during this process. b) Study the effect of percentage theoretical air on the air-fuel ratio and the highest possible temperature that can be obtained. Note: do a parametric study, plot your results, and comment on it
