STEP 1: Convert Input(s) to Base Unit

Pressure Acting at Entry: 9.9E-06 Newton per Square Millimeter --> 9.9 Pascal (Check conversion here)
Initial Thickness: 3.5 Millimeter --> 0.0035 Meter (Check conversion here)
Mean Yield Shear Stress at Entry: 5896.83 --> No Conversion Required
Coefficient of Friction: 0.5 --> No Conversion Required
Factor H at the Entry Point on Workpiece: 3.35 --> No Conversion Required
Factor H at a given Point on Workpiece: 4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_e = (P_e*h_in)/(S_e*exp(μ_rp*(H_in-H_x))) --> (9.9*0.0035)/(5896.83*exp(0.5*(3.35-4)))

Evaluating ... ...

h_e = 8.13261733562491E-06

STEP 3: Convert Result to Output's Unit

8.13261733562491E-06 Meter -->0.00813261733562491 Millimeter (Check conversion here)

FINAL ANSWER

0.00813261733562491 ≈ 0.008133 Millimeter <-- Thickness at Entry
