Design a central annular-groove pressure-fed bearing with an l9yd ratio of 0.5, using SAE grade 20 oil, the lubricant supplied at 30 psig. The exterior oil cooler can maintain the sump temperature at 120°F for heat dissipation rates up to 1500 Btu/h. The load to be carried is 900 lbf at 3000 rev/min. The groove width is 14 in. Use nominal journal diameter d as one design variable and c as the other. Use Trumpler’s criteria for your adequacy assessment.
