Flood Discharge by Fanning's Formula Solution

Follow our step by step solution on how to calculate Flood Discharge by Fanning's Formula?

FIRST Step Consider the formula

Q F = C F \cdot {(A km)}^{\frac{5}{6}}

Next Step Substitute values of Variables

∴

Q F = 2.54 \cdot {(2.4km²)}^{\frac{5}{6}}

Next Step Convert Units

∴

Q F = 2.54 \cdot {(2.4E+6m²)}^{\frac{5}{6}}

Next Step Prepare to Evaluate

∴

Q F = 2.54 \cdot {(2.4E+6)}^{\frac{5}{6}}

Next Step Evaluate

∴

Q F = 526837.181948775m³/s

LAST Step Rounding Answer

∴

Q F = 526837.1819m³/s
