Question
![C,Hs is burned in an engine with a fuel-rich air-fuel ratio. Dry analysis of the exhaust gives
the following volume percents: CO, 14.95%, C,H, 0.75%, CO 0%.
H = 0%, O, 0%, with the rest being
N. Higher heating value of this fuel is Quav 46.9 MJ/kg. Write the balanced chemical
equation for one mole of this fuel at these conditions
Calculate:
(a) Air-fuel ratio.
(b) Equivalence ratio.
(c) Lower heating value of fuel. [MJ/kg]
(d) Energy released when one kg of this fuel is burned in the engine with a combustion
efficiency of 98%. [MJ]](https://content.bartleby.com/qna-images/question/4cf750fd-ff3c-42c4-a663-ef814cf7a067/b92f04c5-98d7-466c-8458-47e1fcf0d0e3/j4rc0h_thumbnail.jpeg)

The reagents enter the reaction at 25°C, and the products are at 727°C. Determine the heat released by the system for ethane combustion with (a) the theoretical stechiometric amount of oxygen (b) the theoretical amount of air (air contains 3.76 kmol of nitrogen per 1 kmol of oxygen). In which case is the heat released by the system larger? Explain why.arrow_forward
