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.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
