Flood Coefficient given Flood Discharge Solution

Follow our step by step solution on how to calculate Flood Coefficient given Flood Discharge?

FIRST Step Consider the formula

C F = (\frac{Q fe}{{(A fd)}^{n}})

Next Step Substitute values of Variables

∴

C F = (\frac{1.08m³/s}{{(2m²)}^{3.1}})

Next Step Prepare to Evaluate

∴

C F = (\frac{1.08}{{(2)}^{3.1}})

Next Step Evaluate

∴

C F = 0.125959453857469

LAST Step Rounding Answer

∴

C F = 0.126
