11.4 The following data refer to a ring-oiled bearing: Kinematic viscosity of the oil at the operating tempera- ture = 12 mm²/s; oil density at operating temperature = 885 kg/m'; bearing pressure = 1 200 kPa; diametral clear- ance ratio = 0,001 5; and journal speed = 1 200 r/min. The L/D ratio 1 and journal diameter termine the Sommerfeld number for this bearing and, us- ing the charts, find (a) the coefficient of friction; (b) the minimum oil film thickness; (c) the oil flow through the bearing due to the pumping action of the journal ; (d) the . 70 mm.
