Liquid ethanol (c2h5oh) is burned with air in a steady-flow, premixed burner. the fuel flow rate is 1.65 gallons per hour (264.2 gallons = 1 m) and the equivalence ratio is 0.53. 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. the mass fraction of oxygen in the products, d. the adiabatic flame temperature, using 1600 and 2400 k as your guesses.
