[DeTomaso] Predicted mileage at 200 MPH

[Mad Dog Antenucci]

Will,
   
  I warned Tom not to pull my finger!
   
  Its called 'pucker factor'  if you can pull your own string out at speed you ain't going fast enough...Remember that Blaine!  ;-]>

The bigger question is how much gas is released by md after the race.

Gauging by the smile on Tom D.'s face, it must have been a lot.

Out of curiosity, I tried to estimate how much gas would be burned to
travel 100 miles at 200 MPH assuming 500 HP is required to maintain speed. I
came up with:


1 HP = 42.21 Btu/min
so, 500 HP = 21,205 Btu/min at 100% efficiency energy conversion
but assuming 33% efficiency, 500 HP requires 63,615 Btu/min 

1 gallon of gasoline contain 115,000 to 125,000 BTUs

at 120,000 Btu/gal, 500 HP will burn about 1/2 gallons per minute
so, at 200 MPH, it takes 30 minutes to travel 100 miles, and 15 gallons of
gasoline.

It seems reasonable, about 6 MPG. I've never done this kind of calculation
before, does anyone see an obvious error?
