Flow of Lubricating Oil Passing through Pad in Terms of Flow Coefficient Solution

Follow our step by step solution on how to calculate Flow of Lubricating Oil Passing through Pad in Terms of Flow Coefficient?

FIRST Step Consider the formula

Q = q f \cdot W \cdot \frac{h^{3}}{A p \cdot μ l}

Next Step Substitute values of Variables

∴

Q = 11.8 \cdot 1800N \cdot \frac{{0.02mm}^{3}}{450mm² \cdot 220cP}

Next Step Convert Units

∴

Q = 11.8 \cdot 1800N \cdot \frac{{2E-5m}^{3}}{0.0004m² \cdot 0.22Pa*s}

Next Step Prepare to Evaluate

∴

Q = 11.8 \cdot 1800 \cdot \frac{{2E-5}^{3}}{0.0004 \cdot 0.22}

Next Step Evaluate

∴

Q = 1.71636363636364E-06m³/s

Next Step Convert to Output's Unit

∴

Q = 1716.36363636364mm³/s

LAST Step Rounding Answer

∴

Q = 1716.3636mm³/s
