Required information

A $6-$cm$-$diameter shaft rotates at $1900$ rpm in a $20-cm-$long bearing with a uniform clearance of $0\mathrm{.}2$ mm $.$ At steady

operating conditions, the bearing in the vicinity of the oil gap are at $50C,$ and the viscosity and thermal conductivity of

lubricating oil are $0\mathrm{.}05N*\frac{s}{m^2}$ and $0\mathrm{.}17\frac{W}{m}*K.$

By simplifying and solving the continuity, momentum, and energy equations, determine the maximum temperature of oil. $($Round the

final answer to one decimal place. You must provide an answer before moving on to the next part.$)$

The maximum temperature of oil is

$C.$

use the solved values of a velocity of $5\mathrm{.}97$ m$/$s and a surface area of $0\mathrm{.}0377$m$^2$
