Following data is provided for a 360o hydrodynamic bearing :
Radial load = 3.2 kN
journal Speed =1490 rpm
journal diameter = 50 mm
bearing length = 50 mm
radial clearance = 0.05 mm
viscosity of lubricant = 25 cP
Considering that the total heat generated in the bearing is taken by the total oil flow in the bearing, determine :
(i) the coefficient of friction
(ii) Power lost in friction
(iii) Minimum oil film thickness
The steam that leaves the super-heater is expanded from 130bar at 535°C to 25.2bar at 310°C in a high pressure turbine. The steam from the exit of the HP turbine is reheated to 535
