Mean velocity in terms of centreline velocity Solution

STEP 0: Pre-Calculation Summary
Formula Used
mean_velocity = Centreline velocity/(1.43*sqrt(Friction factor+1))
V = umax/(1.43*sqrt(f+1))
This formula uses 1 Functions, 2 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
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)
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
Centreline velocity: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Friction factor: 1 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
V = umax/(1.43*sqrt(f+1)) --> 5/(1.43*sqrt(1+1))
Evaluating ... ...
V = 2.4724013328201
STEP 3: Convert Result to Output's Unit
2.4724013328201 Meter per Second --> No Conversion Required
2.4724013328201 Meter per Second <-- Mean velocity

Mean velocity in terms of centreline velocity Formula

mean_velocity = Centreline velocity/(1.43*sqrt(Friction factor+1))
V = umax/(1.43*sqrt(f+1))

What is the meaning of mean velocity?

The time average of the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval T, counted from some fixed time t0. For example, the mean velocity of u component is. The time average of any other quantity can be defined in this manner.

What is the difference between mean velocity and average velocity?

If "mean velocity" is defined as (v+u)/2, while average velocity is the total distance traveled over time, then they are NOT identical.

How to Calculate Mean velocity in terms of centreline velocity?

Mean velocity in terms of centreline velocity calculator uses mean_velocity = Centreline velocity/(1.43*sqrt(Friction factor+1)) to calculate the Mean velocity, The Mean velocity in terms of centreline velocity formula is defined as the average speed of an object we divide the distance traveled by the time elapsed. Mean velocity is denoted by V symbol.

FAQ

What is Mean velocity in terms of centreline velocity?
The Mean velocity in terms of centreline velocity formula is defined as the average speed of an object we divide the distance traveled by the time elapsed and is represented as V = umax/(1.43*sqrt(f+1)) or mean_velocity = Centreline velocity/(1.43*sqrt(Friction factor+1)). Centreline velocity is defined as the maximum velocity in the pipe, so it is, most of the time, larger than the average velocity & The Friction factor or Moody chart is the plot of the relative roughness (e/D) of a pipe against Reynold's number.
