Liquid ethanol (c2hsoh) is burned with air in a steady-flow, premixed burner the fuel flow rate is 0.95 gallons per hour (264.2 gallons =1m^3) and the equivalence ratio is 0.63. the fuel and air enter the combustor at 298 k. determine: a. the heat release rate, in kw. b. the mass flow rate of air, in kg/s. c. (2 pt) the mass fraction of oxygen in the products d. the adiabatic flame temperature, using 1600 and 2400 k as your guesses.
