Runoff Coefficient given Runoff Rate of Rainwater from Bridge during Rainstorm Solution

Follow our step by step solution on how to calculate Runoff Coefficient given Runoff Rate of Rainwater from Bridge during Rainstorm?

FIRST Step Consider the formula

C r = \frac{q p}{1.00083 \cdot I \cdot A catchment}

Next Step Substitute values of Variables

∴

C r = \frac{1.256m³/s}{1.00083 \cdot 16mm/min \cdot 9412m²}

Next Step Convert Units

∴

C r = \frac{1.256m³/s}{1.00083 \cdot 0.0003m/s \cdot 9412m²}

Next Step Prepare to Evaluate

∴

C r = \frac{1.256}{1.00083 \cdot 0.0003 \cdot 9412}

Next Step Evaluate

∴

C r = 0.500009981090959

LAST Step Rounding Answer

∴

C r = 0.5
