Gasoline, C7H17, is burned in a steady state burner with stoichiometric air at Po, To. The gasoline is flowing as a liquid at To to a carburetor where it is mixed with air to produce a fuel air gas mixture at To. The carburetor takes some heat transfer from the hot products to do the heating. After the combustion the products go through a heat exchanger, which they leave at 600 K. The gasoline consumption is 10 kg per hour. How much power is given out in the heat exchanger and how much power does the carburetor need?
