Coefficient of Runoff given Stormwater Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = Peak Rate of Runoff/(Average Rainfall Rate*Drainage Area)
C_r = q_p/(I*A)
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.
Peak Rate of Runoff - (Measured in Cubic Meter per Second) - Peak Rate of Runoff is the maximum rate of discharge during the period of runoff caused by a storm.
Average Rainfall Rate - (Measured in Meter per Second) - Average Rainfall Rate is a measure of the intensity of rainfall by calculating the amount of rain that would fall over a given interval of time.
Drainage Area - (Measured in Square Meter) - Drainage Area is the land region from which all precipitation flows to a common outlet, such as a river, lake, or ocean.

STEP 1: Convert Input(s) to Base Unit

Peak Rate of Runoff: 1.256 Cubic Meter per Second --> 1.256 Cubic Meter per Second No Conversion Required
Average Rainfall Rate: 0.05 Meter per Second --> 0.05 Meter per Second No Conversion Required
Drainage Area: 50 Square Meter --> 50 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = q_p/(I*A) --> 1.256/(0.05*50)

Evaluating ... ...

C_r = 0.5024

STEP 3: Convert Result to Output's Unit

0.5024 --> No Conversion Required

FINAL ANSWER

0.5024 <-- Runoff Coefficient
