Problem #3 (50 pts) Liquid ethanol burns steadily with air supplied at 33 phase) exit at...
An air-breathing gas-turbine jet engine operates at SSSF with complete combustion of 1 kmol / s of liquid ethanol fuel (C₂H₅OH). The given air-fuel ratio is 33 kg-air/kg-fuel. The constant pressure combustion process (2 → 3) results in a small amount of heat transfer out to the surroundings. Assume the inlet air is composed of 21 % O₂ and 79 % N₂(1 O₂+3.76 N₂)FIND the theoretical air-fuel ratio, AFTHEORETICAL= _______ kg-air/kg-fuelFIND the concentration of CO₂ in the exhaust gas on...
Formul Question 2 (50 points): Propane gas and burns with 20% excess air entering (molar C, Hs) at 25 C.I atm enters a reactor operating at steady state at 25 C l atm of the carbon entering with the fuel, 94% s) appears in the products at CO2 and the rest as CO. Heat transfer from the reactor occurs te of 1.4 x 10° kJ per kmol or propane. Use your ideal gas tables to answer this question. ite the...
Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reactor at 0.8 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables CH 25°C CO2, H3O chamber NO.
