3.11 A very long plate of thickness 2H leaves a furnace at temperature yA r To Tf. The plate is cooled as it moves with velocity U through a liquid tank. Because of the high H > U H heat transfer coefficient, the - To surface of the plate is maintained at temperature T,. Determine the steady state two-dimensional temperature distribution in the plate.
