Shear velocity in terms of centreline velocity Solution

STEP 0: Pre-Calculation Summary
Formula Used
shear_velocity = (Centreline velocity-Mean velocity)/3.75
V* = (umax-V)/3.75
This formula uses 2 Variables
Variables Used
Centreline velocity - Centreline velocity is defined as the maximum velocity in the pipe, so it is, most of the time, larger than the average velocity. (Measured in Meter per Second)
Mean velocity - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T. (Measured in Meter per Second)
STEP 1: Convert Input(s) to Base Unit
Centreline velocity: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Mean velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
V* = (umax-V)/3.75 --> (5-10)/3.75
Evaluating ... ...
V* = -1.33333333333333
STEP 3: Convert Result to Output's Unit
-1.33333333333333 Meter per Second --> No Conversion Required
FINAL ANSWER
-1.33333333333333 Meter per Second <-- Shear Velocity

Shear velocity in terms of centreline velocity Formula

shear_velocity = (Centreline velocity-Mean velocity)/3.75
V* = (umax-V)/3.75

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.

How to Calculate Shear velocity in terms of centreline velocity?

Shear velocity in terms of centreline velocity calculator uses shear_velocity = (Centreline velocity-Mean velocity)/3.75 to calculate the Shear Velocity, The Shear velocity in terms of centreline velocity formula is defined as shear-related motion in moving fluids. Shear Velocity is denoted by V* symbol.
