Intensity of Rainfall when Peak Discharge is Considered Solution

Follow our step by step solution on how to calculate Intensity of Rainfall when Peak Discharge is Considered?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

i = \frac{4m³/s}{0.5 \cdot 18km²}

Next Step Convert Units

∴

i = \frac{4m³/s}{0.5 \cdot 1.8E+7m²}

Next Step Prepare to Evaluate

∴

i = \frac{4}{0.5 \cdot 1.8E+7}

Next Step Evaluate

∴

i = 4.44444444444444E-07m/s

LAST Step Convert to Output's Unit

∴

i = 1.6mm/h

Intensity of Rainfall when Peak Discharge is Considered Formula Elements

Variables

Intensity of Rainfall

Go Value of Peak Discharge

Q p = C r \cdot A D \cdot i

Go Coefficient of Runoff when Peak Value is Considered

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

Go Drainage Area when Peak Discharge is Considered

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

Go Peak Discharge for Field Application

Q p = (\frac{1}{3.6}) \cdot C r \cdot i tcp \cdot A D
