Precipitation in Rainfall Runoff Relationship Solution

Follow our step by step solution on how to calculate Precipitation in Rainfall Runoff Relationship?

FIRST Step Consider the formula

P = S r + L

Next Step Substitute values of Variables

∴

P = 0.05m³/s + 49.95m³

Next Step Prepare to Evaluate

∴

P = 0.05 + 49.95

Next Step Evaluate

∴

P = 0.05m

LAST Step Convert to Output's Unit

∴

P = 50mm
