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.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
