Follow our step by step solution on how to calculate Film Thickness in Terms of Flow Coefficient and Flow of Lubricant?

FIRST Step Consider the formula

h = {(Q \cdot A p \cdot \frac{μ l}{W \cdot q f})}^{\frac{1}{3}}

Next Step Substitute values of Variables

∴

h = {(1600mm³/s \cdot 450mm² \cdot \frac{220cP}{1800N \cdot 11.8})}^{\frac{1}{3}}

Next Step Convert Units

∴

h = {(1.6E-6m³/s \cdot 0.0004m² \cdot \frac{0.22Pa*s}{1800N \cdot 11.8})}^{\frac{1}{3}}

Next Step Prepare to Evaluate

∴

h = {(1.6E-6 \cdot 0.0004 \cdot \frac{0.22}{1800 \cdot 11.8})}^{\frac{1}{3}}

Next Step Evaluate

∴

h = 1.95374054045119E-05m

Next Step Convert to Output's Unit

∴

h = 0.0195374054045119mm

LAST Step Rounding Answer

∴

h = 0.0195mm
