As shown in the figure, the right end of a slender, long solid cylindrical metal rod of thermal conductivity

, length

and diameter

(

) is in contact with an infinite liquid heat sink. At steady-state, the temperatures of the right end of the rod and the heat sink are

and

, respectively. If the convection heat transfer coefficient between the liquid heat sink and the right end of the rod is

, then what would be the temperature of the left end of the rod,

, at steady-state? Assume that there is no other heat loss.
