Extreme Rainfall Depth Solution

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

FIRST Step Consider the formula

P m = 42.16 \cdot D^{0.475}

Next Step Substitute values of Variables

∴

P m = 42.16 \cdot {2.42h}^{0.475}

Next Step Prepare to Evaluate

∴

P m = 42.16 \cdot {2.42}^{0.475}

Next Step Evaluate

∴

P m = 0.641523989181647m

Next Step Convert to Output's Unit

∴

P m = 641.523989181647mm

LAST Step Rounding Answer

∴

P m = 641.524mm
