Thanks to those of you who attended our webinar last night on fuel system testing. One of the questions posed was if I could make the formulas for determining required fuel flow available to everyone. I would like to do that here.
The formulas from last night are:
Gravity systems: Horsepower x BSFC x 1.5 x .36 = Ounces/minute
Pressure systems: Horsepower x BSFC x 1.25 x .36 = Ounces/minute
BSFC is brake specific fuel consumption in pounds per horsepower-hour
For those of you who did not listen in, these formulas calculate the amount of fuel that needs to flow through your fuel system when you perform your tests to be sure your system is delivering adequate flow prior to first flight.
