The bottom face of a horizontal slab of thickness 6 mm is maintained at 300°C. The top face is exposed to a flowing gas at 30°C. The thermal conductivity of the slab is 1.5 W m-1K-1 and the convective heat transfer coefficient is 30 W m-2K-1. At steady state, the temperature (in °C) of the top face is
Correct : 271
