Minimum Film Thickness Variable of Bearing Solution

STEP 0: Pre-Calculation Summary
Formula Used
Minimum Film Thickness Variable = Minimum Film Thickness/Radial clearance for bearing
hmin = h°/c
This formula uses 3 Variables
Variables Used
Minimum Film Thickness Variable - Minimum Film Thickness Variable is defined as the ratio of minimum film thickness to radial clearance.
Minimum Film Thickness - (Measured in Meter) - Minimum film thickness is the lowest amount of the thickness of the oil film formed inside the sliding bearing.
Radial clearance for bearing - (Measured in Meter) - Radial clearance for bearing is a measured value of the total movement of one ring relative to the other in a plane perpendicular to the bearing axis.
STEP 1: Convert Input(s) to Base Unit
Minimum Film Thickness: 0.013 Millimeter --> 1.3E-05 Meter (Check conversion here)
Radial clearance for bearing: 0.024 Millimeter --> 2.4E-05 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
hmin = h°/c --> 1.3E-05/2.4E-05
Evaluating ... ...
hmin = 0.541666666666667
STEP 3: Convert Result to Output's Unit
0.541666666666667 --> No Conversion Required
FINAL ANSWER
0.541666666666667 0.541667 <-- Minimum Film Thickness Variable
(Calculation completed in 00.004 seconds)

8 Film Thickness Calculators

Fluid Film Thickness in Terms of Flow of Lubricant
Go Oil film thickness = (Length of slot in direction of flow*12*Dynamic Viscosity of Lubricant*Flow of lubricant from slot/(Breadth of slot for oil flow*Pressure difference between slot sides))^(1/3)
Film Thickness in Terms of Flow Coefficient and Flow of Lubricant
Go Oil film thickness = (Flow of Lubricant*Total Projected Area of Bearing Pad*Dynamic Viscosity of Lubricant/(Load Acting on Sliding Bearing*Flow Coefficient))^(1/3)
Film Thickness in Terms of Absolute Viscosity and Tangential Force
Go Oil film thickness = Dynamic viscosity of oil*Area of moving plate on oil*Velocity of Moving Plate on Oil/Tangential force on moving plate
Minimum Film Thickness given Radius of Bearing
Go Minimum Film Thickness = Radius of Bearing-(Eccentricity in bearing+Radius of Journal)
Minimum Film Thickness of bearing in Terms of Eccentricity Ratio
Go Minimum Film Thickness = Radial clearance for bearing*(1-Eccentricity Ratio of Journal Bearing)
Minimum Film Thickness in Terms of Minimum Film Thickness Variable of Bearing
Go Minimum Film Thickness = Minimum Film Thickness Variable*Radial clearance for bearing
Minimum Film Thickness Variable of Bearing
Go Minimum Film Thickness Variable = Minimum Film Thickness/Radial clearance for bearing
Minimum Film Thickness Variable of Bearing in Terms of Eccentricity Ratio
Go Minimum Film Thickness Variable = 1-Eccentricity Ratio of Journal Bearing
