Gasoline, C₇H₁₇, is burned in a steady-state burner with stoichiometric air at P₀, T₀, shown in Fig. P13.77. The gasoline is flowing as a liquid at T₀ to a carburetor, where it is mixed with air to produce a fuel air–gas mixture at T₀. 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/h. How much power is given out in the heat exchanger, and how much power does the carburetor
need?
