Example: - The load on the journal bearing is 150kN due to turbine shaft of 300mm diameter running at 1800r.p.m. Determine the following:- 1. Length of the bearing if the allowable bearing pressure is 1.6N/mm2 , and 2. Amount of heat to be removed by the lubricant per minute if the bearing temperature is 60 C is 0.02kg/m-s and the bearing clearance is 0.025mm.
