Manning's Roughness Coefficient using Dimensionless Parameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Manning’s Roughness Coefficient = sqrt(Dimensionless Parameter*(Hydraulic Radius of the Channel^(1/3))/116)
n = sqrt(f*(R_H^(1/3))/116)
This formula uses 1 Functions, 3 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Manning’s Roughness Coefficient - Manning’s Roughness Coefficient represents the roughness or friction applied to the flow by the channel.
Dimensionless Parameter - Dimensionless Parameter is a numerical value without units used to express ratios, similarities, or relationships between physical quantities.
Hydraulic Radius of the Channel - (Measured in Meter) - Hydraulic Radius of the 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.

STEP 1: Convert Input(s) to Base Unit

Dimensionless Parameter: 0.03 --> No Conversion Required

What is Inlet flow patterns?

An Inlet has a "gorge" where flows converge before they expand again on the opposite side. Shoal (shallow) areas that extend bayward and oceanward from the gorge depend on inlet hydraulics, wave conditions, and general geomorphology. All these interact to determine flow patterns in and around the inlet and locations where flow channels occur.
