This formula uses 4 Variables
Variables Used
Roughness Coefficient of Conduit Surface - The Roughness Coefficient of Conduit Surface refers to the roughness or irregularity of the inner surface of a conduit through which fluid flows.
Inner Diameter - (Measured in Meter) - The Inner Diameter refers to the diameter of the inner surface or bore of a cylindrical object or conduit.
Energy Loss - (Measured in Joule) - The Energy Loss refers to the dissipation or reduction of energy within a system or process.
Flow Velocity - (Measured in Meter per Second) - The Flow Velocity refers to the speed at which a fluid (such as water) moves through a specific cross-section.
STEP 1: Convert Input(s) to Base Unit
Inner Diameter: 35 Meter --> 35 Meter No Conversion Required
Energy Loss: 2 Joule --> 2 Joule No Conversion Required
Flow Velocity: 1.12 Meter per Second --> 1.12 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
nc = (0.59*di^(2/3)*S^(1/2))/Vf --> (0.59*35^(2/3)*2^(1/2))/1.12
Evaluating ... ...

What is pipe roughness coefficient?

Roughness coefficient is a value used in Manning's formula to determine energy losses of flowing water due to pipe or channel wall roughness. It is based on the material of the pipe. New steel pipe uses a C value of 140, but with use and corrosion a lower value is typically used. For HDPE pipe, a range of C values between 150 and 160 is typical.
