Question

An opaque horizontal plate is well insulated on the
edges and the lower surface. The irradiation on the plate is
3000 W/m2, of which 500 W/m2 is reflected. The plate has a
uniform temperature of 700 K and has an emissive power of
5000 W/m2. Determine the total emissivity and absorptivity
of the plate.
