Rather than "looking it up", perhaps actual measurement is in order.
I have the great planes 2180 with a rayjay turbo. I set up a graduated container, with calibration marks as the test fuel tank, and ran the motor at full power, while measuring the actual consumption. Certainly other methods of measure are available, the point here being "I measured the takeoff power fuel flow, it was "X"." Then I measured the free flow rate of fuel from the fuel tank, measured at the carburator fitting using only the last 1/2 gallon (low head pressure). Then I was able to log with certainty that "This plane delivers more than 3X takeoff fuel flow rate using only the last 1/2 gallon." Which I now know as proven fact. cheers! jg On Sun, Jan 14, 2024, 11:04 Michael R.
