A slab 0.2 m thick with thermal conductivity of 45 W/mK receives heat from a furnace at 500 K both by convection and radiation. The convection coefficient has a value of 50 W/m2K. The surface temperature is 400 K on this side. The heat is transferred to surroundings at T∞2 both by convection and radiation. The convection coefficient on this side being 60 W/m2K. Determine the surrounding temperature. Assume F = 1 for radiation
