Akilogram of jet fuel releases approximately 43,000,000 j of (thermal) energy when combined with air and combusted. current state of the art battery technology can store approximately 200 w-hr of electricity. a. calculate the mass of a battery pack required to replace the energy content of a kilogram of jet fuel on a 1: 1 basis (even though one is chemical potential energy and the other is electrical potential energy). b. the boeing 737 holds approximately 60,000 lbs of fuel at maximum takeoff fuel load (about 1/3 the total takeoff weight). what would be the mass of the battery pack be to replace the fuel on the fully loaded 737 on an energy equivalent basis? c. if a turbofan can convert 30 % of the chemical potential energy in to thrust power and electric motors can convert 90% of the stored electrical energy into thrust, what would be the ratio of exergy extracted from the fuel vs the exergy extracted from the battery?
