Question

Design a journal bearing for a centrifugal pump from the following data: Load on the journal =20,000 N; Speed of the journal =900 r.p.m.; Type of oil is SAE 10, for operating at temperature of 55\deg C; Ambient temperature of oil =15.5\deg C; Maximum bearing pressure for the pump =1.5 N/mm^2. Take journal diameter of 100 mm. Calculate also mass of the lubricating oil required for artificial cooling, if rise of temperature of oil be limited to 10\deg C. Heat dissipation coefficient C =1232 W/m^2/\deg C. Take Specific heat of the oil 1900 J/kg/\deg C
