For a journal bearing of a centrifugal pump from the following data: Diameter of the journal = 100 mm; Length of the journal = 200 mm; Load on the journal 20000 N; Speed of the journal = 1000 rpm; Absolute viscosity of oil = 0.01 kg/ms; Operating temperature of oil = 55C; Ambient temperature of oil = 15C; Maximum bearing pressure for the pump = 1.0 N/mm; Coefficient of the friction = 0.005; Heat dissipation coefficient = 1000 W/m2C. Determine (a) the operating value of bearing characteristic number; (b) the heat generated; (c) the heat dissipated; (d) the thermal equilibrium and calculate also mass of the lubricating oil required for artificial cooling, if rise of temperature of oil be limited to 10C and specific heat of oil = 2000 J/kgC.
