Question

In a journal bearing of 100 mm diameter with a bearing clearance of 0.2 mm, it is found suitable to use lubricating oil with viscosity 60 cp. The shaft runs at 375 r.P.M. And develops a bearing pressure of 1.5 n/mm2. Determine (a) bearing pressure when the shaft speed is increased to 500 rpm, other parameters remaining same. (b) viscosity at 0.15 mm bearing clearance, 450 rpm of shaft and 2.0 n/mm2 bearing pressure
