STEP 0: Pre-Calculation Summary

Formula Used

Shear Velocity 1 = Mean Velocity*sqrt(Friction Factor/8)
V_s = V*sqrt(f/8)
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

Shear Velocity 1 - (Measured in Meter per Second) - Shear Velocity 1 also called friction 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.
Friction Factor - The Friction Factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against Reynold's number.

How does shear stress relate to velocity?

The Newtonian fluids behave according to the law that shear stress is linearly proportional to velocity gradient or rate of shear strain. Thus for these fluids, the plot of shear stress against velocity gradient is a straight line through the origin. The slope of the line determines the viscosity.

Is friction velocity constant?

Whenever there is relative motion between 2 surfaces, friction will occur, whether velocity is constant or changing. This is called kinetic friction. Friction occurs due to irregularities in the surfaces, which hit and interact with each other when 2 surfaces are rubbing past each other.
