A full journal bearing has a nominal diameter of 30 mm and a bearing length of 30 mm. The bearing supports a load of 2000 N, and the journal bearing's speed is 1800 rpm. The radial clearance is 0,025 mm. If the lubricant supply temperature is 40 ºC and the oil to be used is SAE 10. Determine: a) The temperature rise of the lubricant if ΔT is 19 ºC. [14] b) The lubricant flow rate. [3] c) The minimum film thickness. [2] d) The torque required to overcome friction. [3] e) The power dissipated in the bearing. [3
