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/m2is 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.

Gref T; = 700 K
