This formula uses 1 Functions, 4 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
Velocity of Flow in Meter - (Measured in Meter per Second) - Velocity of flow in meter is the flow velocity is defined as a superficial volume average, and it corresponds to a unit volume of the medium, including both the pores and the matrix.
Rugosity Coefficient - Rugosity coefficient is a value used in Manning's formula to determine energy losses of flowing water due to pipe.
Bed Slope of Channel - Bed slope of channel used to calculate the shear stress at the bed of an open channel containing fluid that is undergoing steady, uniform flow.
Hydraulic Mean Depth in Meters - (Measured in Meter) - Hydraulic mean depth in meters the ratio of the cross-sectional area of flow to the free water surface or top width.
STEP 1: Convert Input(s) to Base Unit
Rugosity Coefficient: 0.0177 --> No Conversion Required
Bed Slope of Channel: 0.000333 --> No Conversion Required

What is Kutters Rugosity coefficient?

n is roughness coefficient or rugosity coefficient. The roughness coefficient n is known as Kutter's n. The value of n varies widely depending upon the nature of inside surface of the sewer and its condition. Values of n for different types of surfaces commonly encountered in practice

what is the formula for Hydraulic Depth?

Hydraulic depth, abbreviated as dh, also called hydraulic mean depth, is the area cross-section of water in a pipe or channel divided by the wetting perimeter.

Hydraulic Depth formula
dh=Acw
