De thrust of a shaft is taken by a collar bearing provided with a forced ication system. The lubrication system maintainsa film of oil of erm thickness between the surface of the collar and the bearing The aumal and intemal diameters of collar are 16 and 12 cms. respectively. The thickness of oil film is 0.02 cms. and coefficient of viscosity is 0.91 poise. Find the honse-power lost in overcoming friction when the shaft is ntated at a speed of 350 r.p.m.

Question
The thrust of a shaft is taken by a collar bearing provided with a forced rication system. The lubrication system maintains a film of oil of ilerm thickness between the surface of the collar and the bearing The aemal and intemal diameters of collar are 16 and 12 cms respectively. The thickness of oil film is 0.02 cms. and coefficient of viscosity is 0.91 poise. Find the horse-power lost in overcoming friction when the shaft is ntated at a speed of 350 r.p.m. Skult.
