Q_F = C_F*(A_km)^(5/6)
This formula uses 3 Variables

Variables Used

Flood Discharge by Fanning's Formula - (Measured in Cubic Meter per Second) - Flood Discharge by Fanning's Formula refers to the volume of water flowing through a river or stream during a flood, typically measured in (m³/s) or (cfs).
Fanning's Constant - Fanning's Constant refers to an empirical value used in flood estimation formulas, adjusted for specific regional conditions especially American catchment.
Catchment Area for Flood Discharge - (Measured in Square Meter) - Catchment Area for Flood Discharge refers to an area of land where all water flows to a single stream, river, lake or even ocean, typically in km unit.

STEP 1: Convert Input(s) to Base Unit

Fanning's Constant: 2.54 --> No Conversion Required
Catchment Area for Flood Discharge: 2.4 Square Kilometer --> 2400000 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_F = C_F*(A_km)^(5/6) --> 2.54*(2400000)^(5/6)

Evaluating ... ...

Q_F = 526837.181948775

STEP 3: Convert Result to Output's Unit

526837.181948775 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

526837.181948775 ≈ 526837.2 Cubic Meter per Second <-- Flood Discharge by Fanning's Formula
