Runoff Coefficient given W-Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = Rainfall Depth-(W-Index*Rainfall Duration)
C_r = P_cm-(W*t_r)
This formula uses 4 Variables

Variables Used

Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.
Rainfall Depth - (Measured in Meter) - Rainfall Depth refers to the vertical height of rainwater accumulated over a surface during a specific period, typically measured in millimeters (mm) or inches.
W-Index - (Measured in Meter per Second) - W-Index refers to the uniform rate of infiltration during a rainstorm after initial infiltration capacity has decreased, typically measured in cm/h.
Rainfall Duration - (Measured in Second) - Rainfall duration refers to the length of time over which a rainfall event occurs, typically measured in hours or minutes, affecting runoff and infiltration.

STEP 1: Convert Input(s) to Base Unit

Rainfall Depth: 12 Centimeter --> 0.12 Meter (Check conversion here)
W-Index: 1.714 Centimeter per Hour --> 4.76111111111111E-06 Meter per Second (Check conversion here)
Rainfall Duration: 3.5 Hour --> 12600 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = P_cm-(W*t_r) --> 0.12-(4.76111111111111E-06*12600)

Evaluating ... ...

C_r = 0.06001

STEP 3: Convert Result to Output's Unit

0.06001 --> No Conversion Required

FINAL ANSWER

0.06001 <-- Runoff Coefficient
