STEP 0: Pre-Calculation Summary

Formula Used

Roughness Height of Surface = 12.2*Hydraulic Radius of Channel/(10^(Chezy's Constant/18))
z₀ = 12.2*R_H/(10^(C/18))
This formula uses 3 Variables

Variables Used

Roughness Height of Surface - (Measured in Meter) - Roughness Height of Surface is the height of the roughness of the surface.
Hydraulic Radius of Channel - (Measured in Meter) - Hydraulic Radius of Channel is the ratio of the cross-sectional area of a channel or pipe in which a fluid is flowing to the wet perimeter of the conduit.
Chezy's Constant - The Chezy's constant is a dimensionless quantity that can be calculated by three formulas, namely: Bazin Formula. Ganguillet -Kutter Formula. Manning's Formula.

STEP 1: Convert Input(s) to Base Unit

Hydraulic Radius of Channel: 1.6 Meter --> 1.6 Meter No Conversion Required
