Low Battery
My phone keeps saying this. It probably takes energy to tell me I have low energy,
It takes gas to carry gas. Gas is 6 pounds a gallon. So 30 gallons is 180 pounds.
Here is what a smart person would say:
Assuming the fuel tank is half full on average, the density of fuel is 0.75 ๐๐/๐
0.75kg/l (ref.), so the mass of fuel is 25ร0.75=18.75 ๐๐
25ร0.75=18.75kg
The car and fuel weighs 1218.75 ๐๐
1218.75kg.
The amount of energy used to transport the fuel alone is 18.75รท1218.75=1.5385%
18.75รท1218.75=1.5385%
The fuel used to carry fuel over the car’s lifetime is 7.2ร3000ร0.015385=332.3 ๐
Do there you have it. Nothing is free.
