I may be off base, but the only way I have ever seen this formula used is to determine the amount of volume needed to run a high horsepower motor. If you have a 600hp motor and a 20 gallon per hour pump, you starve the motor. I have a Clay Smith 160 gph on my car, so I am ready for E85 and the excessive volume of fuel it will use.
