Duration given Extreme Rainfall Depth Solution

Follow our step by step solution on how to calculate Duration given Extreme Rainfall Depth?

FIRST Step Consider the formula

D = {(\frac{P m}{42.16})}^{\frac{1}{0.475}}

Next Step Substitute values of Variables

∴

D = {(\frac{641.52mm}{42.16})}^{\frac{1}{0.475}}

Next Step Convert Units

∴

D = {(\frac{64.152cm}{42.16})}^{\frac{1}{0.475}}

Next Step Prepare to Evaluate

∴

D = {(\frac{64.152}{42.16})}^{\frac{1}{0.475}}

Next Step Evaluate

∴

D = 8711.88595042374s

Next Step Convert to Output's Unit

∴

D = 2.41996831956215h

LAST Step Rounding Answer

∴

D = 2.42h
