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

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.

Asatellite that goes around the earth once every 24 hours iscalled a geosynchronous satellite. if a geosynchronoussatellite is in an equatorial orbit, its position appearsstationary with respect to a ground station, and it is known as ageostationary satellite find the radius rof the orbit of a geosynchronous satellite that circles the earth.(note that ris measured from the center of the earth, not the surface.) you mayuse the following constants: the universal gravitational constant g is 6.67 \times 10^{-11}\; {\rm n \; m^2 / kg^2}. the mass of the earth is 5.98 \times 10^{24}\; {\rm kg}. the radius of the earth is 6.38 \times 10^{6}\; {\rm m}.
