E thrust of a shaft is taken by a collar bearing provided with a forced cation system. The lubrication system maintains a film of oil of om thickness between the surface of the collar and the bearing The temal and intemal diameters of collar are 16 and 12 cms. respectively. The thickness of oil film is 0.02 ems. and coefficient of viscosity is 0.91 naise. Find the horse-power lost in overcoming friction when the shaft is uted at a speed of 350 rp.m. Shalt. D 12cm
