Following data is provided for a 360o hydrodynamic bearing :
Radial load = 3.2 kN
journal Speed =1490 rpm
journal diameter = 50 mm
bearing length = 50 mm
radial clearance = 0.05 mm
viscosity of lubricant = 25 cP
Considering that the total heat generated in the bearing is taken by the total oil flow in the bearing, determine :
(i) the coefficient of friction
(ii) Power lost in friction
(iii) Minimum oil film thickness
