Estimate the change in volume of carbon dioxide if 'r' is increased from 10 to 11 (10% increase).
Assume 30 million cars, all use 1m^3 of fuel each year
Efficiency of an Otto Cycle
The Attempt at a Solution
I then looked up a typical value of gamma (1.3), and worked out the efficiency of each
Original = 0.4988
Final = 0.5129
Not sure if this is right, as you weren't given the value of gamma.
Then I'm not entirely sure how to work out how much CO2 is produced from each m^3 of fuel, is it just multiplying by the efficiency?
Or have I gone completely wrong?
