Drainage Area when Peak Discharge is Considered Solution

Follow our step by step solution on how to calculate Drainage Area when Peak Discharge is Considered?

FIRST Step Consider the formula

A D = \frac{Q p}{i \cdot C r}

Next Step Substitute values of Variables

∴

A D = \frac{4m³/s}{1.6mm/h \cdot 0.5}

Next Step Convert Units

∴

A D = \frac{4m³/s}{4.4E-7m/s \cdot 0.5}

Next Step Prepare to Evaluate

∴

A D = \frac{4}{4.4E-7 \cdot 0.5}

Next Step Evaluate

∴

A D = 18000000m²

LAST Step Convert to Output's Unit

∴

A D = 18km²
