Mean Velocity of Flow given Pressure Gradient Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mean Velocity = ((Width^2)/(12*Dynamic Viscosity))*Pressure Gradient
Vmean = ((w^2)/(12*μviscosity))*dp|dr
This formula uses 4 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.
Width - (Measured in Meter) - Width is the measurement or extent of something from side to side.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity of a fluid is the measure of its resistance to flow when an external force is applied.
Pressure Gradient - (Measured in Newton per Cubic Meter) - Pressure Gradient is the change in pressure with respect to radial distance of element.
STEP 1: Convert Input(s) to Base Unit
Width: 3 Meter --> 3 Meter No Conversion Required
Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion here)
Pressure Gradient: 17 Newton per Cubic Meter --> 17 Newton per Cubic Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Vmean = ((w^2)/(12*μviscosity))*dp|dr --> ((3^2)/(12*1.02))*17
Evaluating ... ...
Vmean = 12.5
STEP 3: Convert Result to Output's Unit
12.5 Meter per Second --> No Conversion Required
FINAL ANSWER
12.5 Meter per Second <-- Mean Velocity
(Calculation completed in 00.004 seconds)
