Particle Reynold's Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Particle Reynolds number = Liquid Density*Settling Velocity*Diameter/Dynamic Viscosity
RE = ρ_liquid*v_s*D/μ_viscosity
This formula uses 5 Variables

Variables Used

Particle Reynolds number - Particle Reynolds number describes the dynamics of the fluid flow around the particle: laminar or turbulent.
Liquid Density - (Measured in Kilogram per Cubic Meter) - Liquid Density is mass per unit volume of the liquid.
Settling Velocity - (Measured in Meter per Second) - Settling velocity is defined as the terminal velocity of a particle in still fluid.
Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
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

Liquid Density: 49 Kilogram per Cubic Meter --> 49 Kilogram per Cubic Meter No Conversion Required
Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
Diameter: 10 Meter --> 10 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 = ρ_liquid*v_s*D/μ_viscosity --> 49*1.5*10/1.02

Evaluating ... ...

RE = 720.588235294118

STEP 3: Convert Result to Output's Unit

720.588235294118 --> No Conversion Required

FINAL ANSWER

720.588235294118 ≈ 720.5882 <-- Particle Reynolds number
