Film Thickness in Terms of Absolute Viscosity and Tangential Force Solution

STEP 0: Pre-Calculation Summary

Formula Used

Oil film thickness = Dynamic viscosity of oil*Area of moving plate on oil*Velocity of Moving Plate on Oil/Tangential force on moving plate
h = μ_o*A_po*V_m/P
This formula uses 5 Variables

Variables Used

Oil film thickness - (Measured in Meter) - Oil film thickness is defined as the thickness of the oil film between the two parts in relative motion.
Dynamic viscosity of oil - (Measured in Pascal Second) - Dynamic viscosity of oil is the resistance to movement of one layer of fluid over another.
Area of moving plate on oil - (Measured in Square Meter) - Area of moving plate on oil is the amount of two-dimensional space of the plate that is in contact with the oil film.
Velocity of Moving Plate on Oil - (Measured in Meter per Second) - Velocity of Moving Plate on Oil is the velocity of the plate with respect to fixed plate moving on the oily surface.
Tangential force on moving plate - (Measured in Newton) - Tangential force on moving plate is the force that acts on a moving plate that is sliding onto a oiled surface.

STEP 1: Convert Input(s) to Base Unit

Dynamic viscosity of oil: 490 Centipoise --> 0.49 Pascal Second (Check conversion here)
Area of moving plate on oil: 1750 Square Millimeter --> 0.00175 Square Meter (Check conversion here)
Velocity of Moving Plate on Oil: 5 Meter per Second --> 5 Meter per Second No Conversion Required
Tangential force on moving plate: 214 Newton --> 214 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h = μ_o*A_po*V_m/P --> 0.49*0.00175*5/214

Evaluating ... ...

h = 2.0035046728972E-05

STEP 3: Convert Result to Output's Unit

2.0035046728972E-05 Meter -->0.020035046728972 Millimeter (Check conversion here)

FINAL ANSWER

0.020035046728972 ≈ 0.020035 Millimeter <-- Oil film thickness
