The following data is given for a $\backslash (360^\{\backslash$circ$\}\backslash )$ journal bearing :

Radial load of $3\mathrm{.}2$ kN $,$ Journal speed of $1490$ r$.$p$.$m$,$ journal diameter of $50$ mm $,$ bearing length of $50$ mm $,$ radial clearance of $0\mathrm{.}05$ mm $,$ viscosity of $25$ cP $,$density of lubricant $\backslash (860\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ),$Specific heat of lubricant $\backslash (1\mathrm{.}76\backslash$mathrm$\{$~kJ$\}/\backslash$mathrm$\{$kg$\}^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$

Calculate for the given conditions:

a$.$ Coefficient of friction.

b$.$ Power loss owing to friction.

c$.$ Minimal film thickness

d$.$ Flow requirement of oil in litres $/$ minute

e$.$ Temperature rise in the bearing.
