An automobile engine uses methyl alcohol (CH3OH) as fuel with 200% excess air. Air enters this engine at 1 atm and 25°C. Liquid fuel at 25°C is mixed with this air before combustion. The exhaust products leave the exhaust system at 1 atm and 77°C. Find the specific entropy generation, in kJ/KG per kmol of fuel during the combustion where T0 = 25°C.
