STEP 1: Convert Input(s) to Base Unit

Flow of Lubricant across Bearing Pad: 1717 Cubic Millimeter per Second --> 1.717E-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)
Flow Coefficient: 11.8 --> No Conversion Required
Oil film thickness: 0.02 Millimeter --> 2E-05 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W = Q_bp*A_p*μ_l/(q_f*(h^3)) --> 1.717E-06*0.00045*0.22/(11.8*(2E-05^3))

Evaluating ... ...

W = 1800.66737288136

STEP 3: Convert Result to Output's Unit

1800.66737288136 Newton --> No Conversion Required

FINAL ANSWER

1800.66737288136 ≈ 1800.667 Newton <-- Load Acting on Sliding Bearing
