Intensity of Rain for Intensity Duration Curve Solution

Follow our step by step solution on how to calculate Intensity of Rain for Intensity Duration Curve?

FIRST Step Consider the formula

i idf = \frac{K}{{(T m + b m)}^{0.8}}

Next Step Substitute values of Variables

∴

i idf = \frac{100mm/h}{{(20min + 10min)}^{0.8}}

Next Step Convert Units

∴

i idf = \frac{100mm/h}{{(1200s + 600s)}^{0.8}}

Next Step Prepare to Evaluate

∴

i idf = \frac{100}{{(1200 + 600)}^{0.8}}

Next Step Evaluate

∴

i idf = 6.9100230354019E-08m/s

Next Step Convert to Output's Unit

∴

i idf = 0.248760829274468mm/h

LAST Step Rounding Answer

∴

i idf = 0.2488mm/h
