Manning's Coefficient using Strickler Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Manning’s Roughness Coefficient = (Roughness Value^(1/6))/21
n = (R_a^(1/6))/21
This formula uses 2 Variables

Variables Used

Manning’s Roughness Coefficient - Manning’s Roughness Coefficient represents the roughness or friction applied to the flow by the channel.
Roughness Value - (Measured in Meter) - Roughness Value is the arithmetic average of the absolute values of the roughness profile ordinates.

STEP 1: Convert Input(s) to Base Unit

Roughness Value: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n = (R_a^(1/6))/21 --> (1E-06^(1/6))/21

Evaluating ... ...

n = 0.00476190476190476
