Centreline velocity in terms of shear and mean velocity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Centreline_velocity = (3.75*Shear Velocity)+Mean velocity
umax = (3.75*V*)+V
This formula uses 2 Variables
Variables Used
Shear Velocity - Shear velocity, also called friction velocity, is a form by which a shear stress may be re-written in units of 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
Shear Velocity: 10 Meter per Second --> 10 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
umax = (3.75*V*)+V --> (3.75*10)+10
Evaluating ... ...
umax = 47.5
STEP 3: Convert Result to Output's Unit
47.5 Meter per Second --> No Conversion Required
47.5 Meter per Second <-- Centreline velocity

umax = (3.75*V*)+V

What is Centreline 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.

What is a turbulent velocity profile?

The velocity profile in turbulent flow is flatter in the central part of the pipe (i.e., in the turbulent core) than in laminar flow. The flow velocity drops rapidly, extremely close to the walls. This is due to the diffusivity of the turbulent flow.

How to Calculate Centreline velocity in terms of shear and mean velocity?

Centreline velocity in terms of shear and mean velocity calculator uses Centreline_velocity = (3.75*Shear Velocity)+Mean velocity to calculate the Centreline velocity, The Centreline velocity in terms of shear and mean velocity formula is defined as the maximum velocity in the pipe, so it is, most of the time, larger than the average velocity. Centreline velocity is denoted by umax symbol.
