Particle Reynold's Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Particle Reynolds number = Mass Density of Fluid*Settling Velocity*Diameter/Dynamic Viscosity
RE = ρ_f*V_s*D/μ_viscosity
This formula uses 5 Variables

Variables Used

Particle Reynolds number - The Particle Reynolds number refers to the dynamics of the fluid flow around the particle.
Mass Density of Fluid - (Measured in Kilogram per Cubic Meter) - Mass Density of Fluid refers to the mass per unit volume of the fluid, typically expressed in kilograms per cubic meter (kg/m³).
Settling Velocity - (Measured in Meter per Second) - The Settling Velocity refers to the rate at which a particle suspended in a fluid (like water or air) falls under the influence of gravity until reaches a constant speed.
Diameter - (Measured in Meter) - The Diameter refers to 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 refers to the property of a fluid that quantifies its internal resistance to flow when subjected to an external force or shear stress.

STEP 1: Convert Input(s) to Base Unit

Mass Density of Fluid: 1000 Kilogram per Cubic Meter --> 1000 Kilogram per Cubic Meter No Conversion Required
Settling Velocity: 1.5 Meter per Second --> 1.5 Meter per Second No Conversion Required
Diameter: 0.06 Meter --> 0.06 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_f*V_s*D/μ_viscosity --> 1000*1.5*0.06/1.02

Evaluating ... ...

RE = 88.2352941176471

STEP 3: Convert Result to Output's Unit

88.2352941176471 --> No Conversion Required

FINAL ANSWER

88.2352941176471 ≈ 88.23529 <-- Particle Reynolds number
