Q. 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, TQ 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, TP, (in °C) of the side which is exposed to the fluid is____________________(correct to two decimal places).
