Liquid propane (C3H8) enters a combustion chamber at 25°C at a rate of
0.07 kg/min where it is mixed and burned with 40 percent excess air that
enters the combustion chamber at 7°C. An analysis of the combustion
gases reveals that all the hydrogen in the fuel burns to H,0 but only 75
percent of the carbon burns to CO, with the remaining 25 percent forming
CO. determine (a) the balanced equation for actual combustion process
and (b) the mass flow rate of air.
Liquid propane (C 3 H 8 ) enters a combustion chamber at 25 °C at a rate of 0.05
kg/min where it is mixed and burned with theoretical air that enters the
combustion chamber at 7 °C. an analysis of combustion gases reveals that all the
hydrogen in the fuel burns to H 2 O but only but only 90% of carbon burn to CO 2
with the remaining 10% forming Co if the exit temperature of combustion gases
is 1500 K (a) the mass flow rate of air and (b) the rate of heat transfer from the
combustion chamber
Using Hess' Law, calculate for the heat of combustion of a
1.5 liter propene (C3H6) at 14.5 psi and 80.6°F that is
completely burned in air. Assume that all the water
produced during the reaction is in liquid state.
The standard enthalpy of formation of propene, C3H6 is
+20.6 kJ/mol.
The heats of formation of CO₂(g) and H₂O(l) are -394 kJ/mol
and -285.8 kJ/, respectively.
