Assume the cycle thermal efficiency is the same as part f) and the volumetric efficiency is 1.7 for a certain operating condition with engine speed at 1500 rpm. each cylinder has one injector and each injector has 6 nozzle holes with a diameter of 200 micrometer. the discharge coefficient of the injector nozzle is 0.75. if the injection pressure is 1200 bar across the injector nozzle, and the injection duration is 8 crank angle degrees. what will 2 be the air-fuel ratio and imep assuming 98% combustion efficiency? fuel density is 800 kg/m3 . heating value of the fuel is = 42500

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
