STEP 0: Pre-Calculation Summary
Formula Used
Friction Factor = 8*(Friction Velocity/Mean Velocity)^2
f = 8*(Vf/Vmean)^2
This formula uses 3 Variables
Variables Used
Friction Factor - The Friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against Reynold's number.
Friction Velocity - (Measured in Meter per Second) - Friction velocity, also called Shear velocity, is a form by which a shear stress may be re-written in units of velocity.
Mean Velocity - (Measured in Meter per Second) - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T.
STEP 1: Convert Input(s) to Base Unit
Friction Velocity: 6 Meter per Second --> 6 Meter per Second No Conversion Required
Mean Velocity: 10.1 Meter per Second --> 10.1 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
