$4$: A full journal bearing has a joumal diameter of $25$ mm $,$ with a unilateral tolerance of $-$

$0\mathrm{.}03$ mm $.$ The bushing bore has a diameter of $25\mathrm{.}03$ mm and a unilateral tolerance of

$0\mathrm{.}04$ mm $.$ The $\frac{l}{d}$ ratio is $\frac{1}{2}.$ The load is $1\mathrm{.}5$ kN and the journal runs at $1200re\frac{v}{m}in.$

The operating temperature is $150F$ and SAE grade $40$ oil is used. Find the minimum

film thickness $($hio$),$ the power loss from friction in horsepower, and the side flow $(Q_s)$

for the minimum elearance assembly.
