A previous part of the question says that the total electrical energy the battery can produce is 5832000 Joules. The battery has a mass of 18.1 kg. What total mass of such batteries would be required to deliver the same effective mechanical energy as 12 gallons of gasoline? Assume that the efficiency of an electrically powered car is 2.5 times that of a gasoline-powered car for the conversion to mechanical energy, and that energy content of 1 gallon of gas =1.32×10^8 Joules
A previous part of the question says that the total electrical energy the battery can produce is 5832000 Joules.
The battery has a mass of 18.1 kg. What total mass of such batteries would be required to deliver the same effective mechanical energy as 12 gallons of gasoline? Assume that the efficiency of an electrically powered car is 2.5 times that of a gasoline-powered car for the conversion to mechanical energy, and that energy content of 1 gallon of gas =1.32×10^8 Joules.
The energy content of 1 gallon of gas =1.32×10^8 Joules.
So the energy content of 12 gallons of gasoline=12×1.32×10^8 Joules=15.84×10^8 Joules.
Let the efficiency of an gasoline powered car is n .
So the effective mechanical energy for 12 gallons of gasoline is
Let p number of batteries are required to produce this much effective mechanical energy.
