Problem $12-10$

A full journal bearing has a shaft diameter of $3\mathrm{.}000$ in with a unilateral tolerance of $0\mathrm{.}0004$ in $.$ The $\backslash ($ l $/$ d $\backslash )$ ratio is unity. The bushing has a bore diameter of $3\mathrm{.}003$ in with a unilateral tolerance of $0\mathrm{.}0012$ in $.$ The SAE $40$ oil supply is in an axial$-$groove sump with a steady$-$state temperature of $\backslash (140^\{\backslash$circ$\}\backslash$mathrm$\{$F$\}\backslash ).$ The radial load is $675$ lbf $.$ Estimate the average film temperature, the minimum film thickness, the heat loss rate, and the lubricant side$-$flow rate for the minimum clearance assembly, if the journal speed is $\backslash (10\backslash$mathrm$\{$rev$\}/\backslash$mathrm$\{$s$\}\backslash ).$
