This formula uses 6 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 Stress - (Measured in Pascal) - Shear Stress is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress.
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.
Distance between plates - Distance between plates is the length of the space between two points.
Horizontal Distance - (Measured in Meter) - Horizontal Distance denotes the instantaneous horizontal distance cover by an object in a projectile motion.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied.

STEP 1: Convert Input(s) to Base Unit

Shear Stress: 45.9 Pascal --> 45.9 Pascal No Conversion Required
Pressure Gradient: 17 Newton per Cubic Meter --> 17 Newton per Cubic Meter No Conversion Required
Distance between plates: 2.9 --> No Conversion Required
Horizontal Distance: 4 Meter --> 4 Meter No Conversion Required
Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_mean = (𝜏+dp|dr*(0.5*D-R))*(D/μ) --> (45.9+17*(0.5*2.9-4))*(2.9/1.02)

Evaluating ... ...

V_mean = 7.25000000000001

STEP 3: Convert Result to Output's Unit

7.25000000000001 Meter per Second --> No Conversion Required

FINAL ANSWER

7.25000000000001 ≈ 7.25 Meter per Second <-- Mean Velocity
