Calculate the nitric oxide (no) emission index (eino in units of g of no emitted per kg of fuel burned) for a combustor burning ethane (c2h6) with air, given the following exhaust mole fraction measurements: χco2 = 0.110, χo2 = 0.005, χh2o = 0.160, and χno = 185·10-6. you may assume that the exhaust co and unburned hydrocarbon mole fractions are negligible. does the numerical value of eino depend on whether the exhaust measurements are reported on a wet basis or on a dry basis?
emission index no = (molefractionno/sum of all mole fraction)*(x*molecularweightno/mole cularweightfuel); x is 2.

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.
