Question
Gasoline (assumed C3H18) is burned steadily with air in the combustion chamber of a jet
engine. If the air-fuel ratio (A/F) is 18 kg air/kg fuel, determine the percentage of theoret-
ical air used during this process. Draw a simple block diagram for the combustion chamber
of the jet engine as a control volume, clearly showing the control surface and the input
reactants and the output products (without O2) simple with arrows. Assume the jet engine
is stationary. Air contains 21% O2 and 79% N2 by mole.
Take the molar mass of air, Mair= 29 kg/kmol.
