Flow Coefficient in Terms of Flow of Lubricant through Pad Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

q f = 1600mm³/s \cdot 450mm² \cdot \frac{220cP}{1800N \cdot ({0.02mm}^{3})}

Next Step Convert Units

∴

q f = 1.6E-6m³/s \cdot 0.0004m² \cdot \frac{0.22Pa*s}{1800N \cdot ({2E-5m}^{3})}

Next Step Prepare to Evaluate

∴

q f = 1.6E-6 \cdot 0.0004 \cdot \frac{0.22}{1800 \cdot ({2E-5}^{3})}

LAST Step Evaluate

∴

q f = 11
