Particle Reynold's Number Solution

Follow our step by step solution on how to calculate Particle Reynold's Number?

FIRST Step Consider the formula

RE = ρ f \cdot V s \cdot \frac{D}{μ viscosity}

Next Step Substitute values of Variables

∴

RE = 1000kg/m³ \cdot 1.5m/s \cdot \frac{0.06m}{10.2P}

Next Step Convert Units

∴

RE = 1000kg/m³ \cdot 1.5m/s \cdot \frac{0.06m}{1.02Pa*s}

Next Step Prepare to Evaluate

∴

RE = 1000 \cdot 1.5 \cdot \frac{0.06}{1.02}

Next Step Evaluate

∴

RE = 88.2352941176471

LAST Step Rounding Answer

∴

RE = 88.2353
