The thrust of a shaft is taken by a collar bearing filled with a forced lubrication system which maintains a film of oil of constant thickness 0.3 mm between the surface of the collar and the bearing. The outer and inner diameters of the collar are 156 mm and 120 mm respectively. The coefficient of viscosity of the oil is 1.2 poise. Calculate the power lost in friction of the bearing when the shaft rotates at 500 revolutions per minute.
