Coefficient of Runoff given Peak Rate of Runoff Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = (36*Peak Drainage Discharge by Rational Formula)/(Area of Catchment*Critical Rainfall Intensity)
C_r = (36*Q_R)/(A_c*P_c)
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 Drainage Discharge by Rational Formula - (Measured in Cubic Meter per Second) - The Peak Drainage Discharge by Rational Formula estimates stormwater runoff using parameters such as rainfall intensity, catchment area, and runoff coefficient to determine the maximum flow rate.
Area of Catchment - (Measured in Square Meter) - Area of Catchment refers to the area of land where all water flows to a single stream, river, lake or even ocean.
Critical Rainfall Intensity - (Measured in Centimeter per Hour) - Critical Rainfall Intensity is the precipitation rate at which surface runoff initiates, leading to increased risk of flooding or other hydrological hazards.

STEP 1: Convert Input(s) to Base Unit

Peak Drainage Discharge by Rational Formula: 4166.67 Cubic Meter per Second --> 4166.67 Cubic Meter per Second No Conversion Required
Area of Catchment: 15 Hectare --> 150000 Square Meter (Check conversion here)
Critical Rainfall Intensity: 2.01 Centimeter per Hour --> 2.01 Centimeter per Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = (36*Q_R)/(A_c*P_c) --> (36*4166.67)/(150000*2.01)

Evaluating ... ...

C_r = 0.497512835820896

STEP 3: Convert Result to Output's Unit

0.497512835820896 --> No Conversion Required

FINAL ANSWER

0.497512835820896 ≈ 0.497513 <-- Runoff Coefficient
