Duration of Rainfall Excess Solution

Follow our step by step solution on how to calculate Duration of Rainfall Excess?

FIRST Step Consider the formula

D = 1.1 \cdot T p1

Next Step Substitute values of Variables

∴

D = 1.1 \cdot 26.48h

Next Step Convert Units

∴

D = 1.1 \cdot 95328s

Next Step Prepare to Evaluate

∴

D = 1.1 \cdot 95328

Next Step Evaluate

∴

D = 104860.8s

LAST Step Convert to Output's Unit

∴

D = 29.128h
