go full throttle all the time.
Full throttle = 6MPG x 13.2 gallon = 79.2 miles per tank |

If you had a FR-S fuel pump (pumping fuel out), in the tank, with 12 gallons of gasoline, how long would it take to raise the temperature of the gasoline 1.0 degree C . Allow me to get you started: (or you can use @Overdrive 's method "The answer is: Imhotep is invisible, and the train will arrive in Nova Scotia in 27 hours".) humfrz |

But regardless, the unknown value for the calculation is the amount of heat generated by the pump (Btu/h). BTW, the mass (and specific heat) of gasoline is not the same as it is for water. BTW, weren't you an OSU Engineering grad? |

True, that is the unknown True (just substitute gasoline for water in the equation) Well, you got the OSU grad correct ....... but NOT an engineer. My first year I was in the college of engineering, with plans on transferring to the Colorado School of Mines, to become a geophysical engineer. The problem was ....... I wasn't smart enough, so I shifted gears and went into the college of agriculture. humfrz |

Anyone want to check to see how much current the fuel pump draws? That's your energy input. I also don't think heat loss to the environment is insignificant. |

Anyway, the tank is designed to keep a couple of gallons in reserve for those brave souls who want to let the needle go past the "E", and to try to keep the tank from going completely dry since that's where real damage to the pump, fuel system, and engine can occur. So as a rough number, I'd say maybe 11.5 gallons is what you have from full to the empty line. That leaves you a little less than 2 gallons in reserve so that the tank doesn't truly go empty unless someone pushes it to exhaustion.

Actually, its the current (amps) X the voltage. (watts) |

Even if the pump did draw 20A, it would be wrong to assume that 240W of heat was being produced. Most of the power goes to pumping the fuel, only a fraction goes to generating heat.
