STEP 1: Convert Input(s) to Base Unit
Fuller's Constant for FPS: 28 --> No Conversion Required
Area of Basin: 2.6 Square Mile --> 2.59998918580837 Square Mile (US Survey) (Check conversion ​here)
Time Period for a Flood Discharge: 2.2 Year --> 2.2 Year No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
QFLF = CFLF*((A1)^(0.8))*(1+0.8*log(Tm,e))*(1+2*(A1)^(-0.2)) --> 28*((2.59998918580837)^(0.8))*(1+0.8*log(2.2,e))*(1+2*(2.59998918580837)^(-0.2))
Evaluating ... ...
QFLF = 321.30842160842
STEP 3: Convert Result to Output's Unit
9.09844128351247 Cubic Meter per Second -->321.30842160842 Cubic Foot per Second (Check conversion ​here)
FINAL ANSWER
321.30842160842 321.3084 Cubic Foot per Second <-- Flood Discharge by Fuller's Formula in FPS
(Calculation completed in 00.020 seconds)
