STEP 1: Convert Input(s) to Base Unit

Flow of Lubricant: 1600 Cubic Millimeter per Second --> 1.6E-06 Cubic Meter per Second (Check conversion here)
Total Projected Area of Bearing Pad: 450 Square Millimeter --> 0.00045 Square Meter (Check conversion here)
Dynamic Viscosity of Lubricant: 220 Centipoise --> 0.22 Pascal Second (Check conversion here)
Load Acting on Sliding Bearing: 1800 Newton --> 1800 Newton No Conversion Required
Flow Coefficient: 11.8 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = (Q*A_p*μ_l/(W*q_f))^(1/3) --> (1.6E-06*0.00045*0.22/(1800*11.8))^(1/3)

Evaluating ... ...

h = 1.95374054045119E-05

STEP 3: Convert Result to Output's Unit

1.95374054045119E-05 Meter -->0.0195374054045119 Millimeter (Check conversion here)

FINAL ANSWER

0.0195374054045119 ≈ 0.019537 Millimeter <-- Oil Film thickness
