Shear Stress in Fluid or Oil of Journal Bearing Solution

Follow our step by step solution on how to calculate Shear Stress in Fluid or Oil of Journal Bearing?

FIRST Step Consider the formula

𝜏 = \frac{π \cdot μ \cdot D s \cdot N}{60 \cdot t}

Next Step Substitute values of Variables

∴

𝜏 = \frac{π \cdot 8.23N*s/m² \cdot 14.9008m \cdot 1.0691rev/min}{60 \cdot 4.6232m}

Next Step Substitute values of Constants

∴

𝜏 = \frac{3.1416 \cdot 8.23N*s/m² \cdot 14.9008m \cdot 1.0691rev/min}{60 \cdot 4.6232m}

Next Step Convert Units

∴

𝜏 = \frac{3.1416 \cdot 8.23Pa*s \cdot 14.9008m \cdot 0.0178Hz}{60 \cdot 4.6232m}

Next Step Prepare to Evaluate

∴

𝜏 = \frac{3.1416 \cdot 8.23 \cdot 14.9008 \cdot 0.0178}{60 \cdot 4.6232}

Next Step Evaluate

∴

𝜏 = 0.0247471295956906Pa

Next Step Convert to Output's Unit

∴

𝜏 = 0.0247471295956906N/m²

LAST Step Rounding Answer

∴

𝜏 = 0.0247N/m²
