A journal bearing has a clearance of 0.5 mm. The journal has a diameter of 100 mm and rotates at 3600 rpm within the bearing. The journal is lubricated by an oil having a density of 800 kg/m3, a viscosity of 0.01 kg/(ms), and a thermal conductivity of 0.14 W/(mK). Both the journal and the bearing temperatures are maintained at 60?C. Calculate the rate of heat transfer from the bearing and the power required for rotation per unit length.GIVENA journal bearingDiameter (D) = 100 mm = 0.1 mClearance (H) = 0.5 mm = 0.0005 mRotational speed (ω) = 3600 rpmOil propertiesDensity (ρ) = 800 kg/m3Viscosity (μ) = 0.01 kg/(ms)Thermal conductivity (k) = 0.14 W/(m K)Temperature of both surface (Tb) = 60?CASSUMPTIONSSteady stateUniform and constant surface temperaturesConstant fluidproperties
