A journal bearing using SAE$30$ has a diameter of $50$ mm and length of $25$ mm $.$

The load is $2$ kN at a journal speed of $800$ rpm $.$ If the average film temperature

is $46\mathrm{.}5C$ and the clearance is $0\mathrm{.}05$ mm $,$ calculate the frictional power loss,

maximum pressure and minimum film thickness.
