Shear Velocity given Centreline Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Shear Velocity 1 = (Centreline Velocity-Mean Velocity)/3.75
V_s = (U_max-V)/3.75
This formula uses 3 Variables

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.
Centreline Velocity - (Measured in Meter per Second) - Centreline Velocity is defined as the maximum velocity in the pipe, so it is, most of the time, larger than the average 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

Centreline Velocity: 2.88 Meter per Second --> 2.88 Meter per Second No Conversion Required
Mean Velocity: 2 Meter per Second --> 2 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_s = (U_max-V)/3.75 --> (2.88-2)/3.75

Evaluating ... ...

V_s = 0.234666666666667

STEP 3: Convert Result to Output's Unit

0.234666666666667 Meter per Second --> No Conversion Required

FINAL ANSWER

0.234666666666667 ≈ 0.234667 Meter per Second <-- Shear Velocity 1

Is friction velocity constant?

If a block is moving on a rough surface, and friction is the only force acting on it, it is not moving with a constant velocity. It is slowing down or already stopped. In order for a block to be moving at a constant velocity, the forces must be balanced.

What is cenreline velocity ?

Center-line velocity is usually the maximum velocity in the pipe, so it is, most of the time, larger than the average velocity. Average velocity is easy to calculate: so if you know the mass flow rate, the density, and the pipe cross-sectional area, you can calculate the average velocity.
