: In a journal bearing of length 500 mm, a 200 mm dliameter shaft is rotating at 1000 r.p.m. The uniform space between the shaft and the journal bearing is completely filled with an oil (Newtonian fluid) having a viscosity of 900 centipoise. If energy is being dissipated as kJ while overcoming friction and heat at the rate of 15.5 see the velocity profile in the oil is linear, then the thickness of the oil layer between the shaft and the bearing is (B) I mm (D) 3 mm (A) 5 mm (C) 2 mm
