Liquid propane (C3H8) enters a combustion chamber at 25°C at a rate of 0.05 kg/min where it is mixed and burned with 50 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 H2O but only 90 percent of the carbon burns to CO2, with the remaining 10 percent forming CO. If the exit temperature of the combustion gases is 1500 K, determine
1-The balanced chemical equation for the actual process
2-Air- Fuel ratio
3-The mass flow rate of air
Calculate the enthalpy of combustion of propane C3H8 at 25 oC in both kJ/kg and kJ/mole under the following conditions:-
1- gaseous propane with H2O liquid in the products.
2- gaseous propane with H2O vapor in the products
3- liquid propane with H2O liquid in the products
4- liquid propane with H2O vapor in the products
note: the enthalpy of evaporation of propane at 25 oC is 425 kJ/kg
Determine the enthalpy of combustion (in kJ) when fully-consuming a 23-L tank of ethane. The ethane inside the tank is pressurized to 8 atm at 30 ⁰C.
