Question
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 To2 both by convection and radiation. The
convection coefficient on this side being 60 W/
m2K.
Determine the surrounding temperature.
