Design a Journal bearing for a Centrifugal pump running at 1440 rpm. The diameter of the journal is 100 mm and load on each bearing is 20kN. The factor ZN/P may be taken as 28 for Centrifugal pump bearings. The bearing is running at 75 0C temperature and atmospheric temperature is 30 0C. The energy dissipation coefficient is 875 W/m2 0C. Take diametral clearance as 0.1 mm.
