Runoff for Phi Index for Practical Use Solution

Follow our step by step solution on how to calculate Runoff for Phi Index for Practical Use?

FIRST Step Consider the formula

R 24-h = I - (φ \cdot 24)

Next Step Substitute values of Variables

∴

R 24-h = 0.8cm/h - (0.0279 \cdot 24)

Next Step Prepare to Evaluate

∴

R 24-h = 0.8 - (0.0279 \cdot 24)

Next Step Evaluate

∴

R 24-h = 0.001304m

LAST Step Convert to Output's Unit

∴

R 24-h = 0.1304cm
