Mean Velocity given Shear Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Velocity = 3.75*Shear Velocity-Centreline Velocity
V = 3.75*V_'-U_max
This formula uses 3 Variables

Variables Used

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.
Shear Velocity - (Measured in Meter per Second) - Shear velocity, 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.

STEP 1: Convert Input(s) to Base Unit

Shear Velocity: 6 Meter per Second --> 6 Meter per Second No Conversion Required
Centreline Velocity: 2.88 Meter per Second --> 2.88 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V = 3.75*V_'-U_max --> 3.75*6-2.88

Evaluating ... ...

V = 19.62

STEP 3: Convert Result to Output's Unit

19.62 Meter per Second --> No Conversion Required

FINAL ANSWER

19.62 Meter per Second <-- Mean Velocity

(Calculation completed in 00.004 seconds)

What is meant by flow velocity?

Flow velocity is the vector field that is used to describe fluid motion in a mathematical manner. The entire length of the flow velocity is referred to as the flow speed. Flow velocity in fluids is the vector field that provides the velocity of fluids at a certain time and position.

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.

How to Calculate Mean Velocity given Shear Velocity?

Mean Velocity given Shear Velocity calculator uses Mean Velocity = 3.75*Shear Velocity-Centreline Velocity to calculate the Mean Velocity, The Mean Velocity given Shear Velocity formula is defined as the velocity of a fluid at a fixed point, over a somewhat arbitrary time interval counted from some fixed time. Mean Velocity is denoted by V symbol.

How to calculate Mean Velocity given Shear Velocity using this online calculator? To use this online calculator for Mean Velocity given Shear Velocity, enter Shear Velocity (V_') & Centreline Velocity (U_max) and hit the calculate button.
