Mean Velocity of Flow given Pressure Gradient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Velocity = ((Width^2)/(12*Dynamic Viscosity))*Pressure Gradient
V_mean = ((w^2)/(12*μ))*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 refers to the internal resistance of a fluid to flow when a force is applied.
Pressure Gradient - (Measured in Newton per Cubic Meter) - The Pressure Gradient refers to the rate of change of pressure in a particular direction indicating how quickly the pressure increases or decreases around a specific location.

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

V_mean = ((w^2)/(12*μ))*dp|dr --> ((3^2)/(12*1.02))*17

Evaluating ... ...

V_mean = 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
