An opaque horizontal plate has a surface area of 3 m2 and its edges and base are perfectly insulated. The plate is irradiated uniformly on the top at a rate (for the entire plate) of 1300 W. Consider steady-state conditions where 1000 W of the incident radiation is absorbed, the plate is at a temperature 500 K, and The heat transferred to the surface by convection is 300 W. Determine the irradiance G, emissive power E, radiosity J, absorptivity a, reflectivity p and emissivity e.
