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. (1 pt) the heat release rate, in kw. b. (2 pts) the mass flow rate of air, in kg/s. c. (1 pt) the mass fraction of oxygen in the products. d. (3 pts) the adiabatic flame temperature, using 1600 and 2400 k as your guesses.
