Centreline Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Centreline Velocity = 1.43*Mean Velocity*sqrt(1+Friction Factor)
U_max = 1.43*V*sqrt(1+f)
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

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.
Friction Factor - The Friction Factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against Reynold's number.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity: 2 Meter per Second --> 2 Meter per Second No Conversion Required
Friction Factor: 0.16 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

U_max = 1.43*V*sqrt(1+f) --> 1.43*2*sqrt(1+0.16)

Evaluating ... ...

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.

Does turbulence increase with velocity?

As can be seen in this equation, Re increases as velocity increases and decreases as viscosity increases. Therefore, high velocities and low blood viscosity are more likely to cause turbulence.
