What is viscous resistance of journal bearing?

Let us consider that a shaft is rotating in a journal bearing and think that oil is used as a lubricant in order to fill the clearance between the shaft and journal bearing. Therefore oil will offer viscous resistance to the rotating shaft.

What is shear force in the oil?

Shear forces acting tangentially to a surface of a solid body cause deformation. When the fluid is in motion, shear stresses are developed due to the particles in the fluid moving relative to one another.

How to Calculate Power Absorbed in Overcoming Viscous Resistance in Journal Bearing?

Power Absorbed in Overcoming Viscous Resistance in Journal Bearing calculator uses Power Absorbed = (Viscosity of Fluid*pi^3*Shaft Diameter^3*Mean Speed in RPM^2*Length of Pipe)/Thickness of Oil Film to calculate the Power Absorbed, Power Absorbed in Overcoming Viscous Resistance in Journal Bearing depends on the viscosity of the lubricant, the dimensions of the bearing (including the radius and length), the rotational speed of the shaft, and the clearance between the shaft and the bearing. The power absorption is directly proportional to the lubricant's viscosity, the bearing dimensions, the square of the rotational speed, and inversely proportional to the clearance between the shaft and the bearing. Power Absorbed is denoted by P symbol.
