STEP 0: Pre-Calculation Summary
Formula Used
Reynolds Number = (Density of Fluid*Flow Velocity*Chord Length of Airfoil)/Dynamic Viscosity
Re = (ρfluid*Vf*c)/μviscosity
This formula uses 5 Variables
Variables Used
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
Density of Fluid - (Measured in Kilogram per Cubic Meter) - Density of Fluid is defined as the mass of fluid per unit volume of the said fluid.
Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Chord Length of Airfoil - (Measured in Meter) - The Chord Length of Airfoil is the distance from the leading edge to the trailing edge.
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.
STEP 1: Convert Input(s) to Base Unit
Density of Fluid: 1.225 Kilogram per Cubic Meter --> 1.225 Kilogram per Cubic Meter No Conversion Required
Flow Velocity: 1.12 Meter per Second --> 1.12 Meter per Second No Conversion Required
Chord Length of Airfoil: 0.45 Meter --> 0.45 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
Re = (ρfluid*Vf*c)/μviscosity --> (1.225*1.12*0.45)/1.02
Evaluating ... ...
Re = 0.605294117647059
STEP 3: Convert Result to Output's Unit
0.605294117647059 --> No Conversion Required
FINAL ANSWER
0.605294117647059 0.605294 <-- Reynolds Number
