A plane slab of thickness L and thermal conductivity k is heated with a fluid on one side  and the other side  is maintained at a constant temperature, T_Q of 25^°C, as shown in the figure. The fluid is at 45^°C and the surface heat transfer coefficient, h, is  The steady state temperature. T_P (in ^°C) of the side which is exposed to the fluid is _________ (correct to two decimal places).
