A plane slab of thickness L and thermal conductivity k is heated with a fluid on one side (P), and the other side (Q) 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 10 W/m²K. The steady state temperature. T_p (in °C) of the side which is exposed to the fluid is (correct to two decimal places).
