Unformatted text preview: Assignment 3 1. In a combustor, butane (C 4 H 10 ) is used as the fuel with an air fuel ratio of 22, by mass. Calculate the fuel utilization efficiency of this process if the exhaust gas has a temperature of 800K. 2. In a constant pressure combustion, a stoichiometric butane (C 4 H 10 ) – air mixture at 298 K reacts to form a mixture of gaseous products. Calculate the adiabatic flame temperature, assuming no dissociation, using a trial and error method. 3. Using the single-step global mechanism for propane combustion with air, calculate the initial rates of CO 2 formation for Φ =1, P=2atm, T=1600K 4 Using the single-step global mechanism for butane combustion with air, calculate the initial rates of CO 2 formation for Φ =1, P=2atm, T=1500K 5 Use the single step global mechanism for combustion of methane with air, calculate the mean fuel consumption rate for Ф = 1, P = 1 atm and T = 1600 K. State your assumptions. 6 Calculate the mean fuel consumption rate for the stoichiometric combustion of n- hexane (C 6 H 14 ) in air. Assume the fuel and air are originally at 298 K and atmospheric pressure; and assume T i = 500 K and T f = 2300 K. 7. Consider the combustion of hydrogen (H 2 ) in a steady-flow reactor as shown in the sketch. The heat loss through the reactor walls per unit mass flow ( ) is 187 kJ/kg. The equivalence ratio is 0.5 and the pressure is 5 atm....
