Consider a hemispherical furnace of diameter D = 6 m with a flat base. The dome of the furnace has an emissivity of 0.7 and the flat base is a blackbody. The base and the dome are maintained at uniform temperatures of 300 K and 1200 K, respectively. Under steady-state conditions, the rate of radiation heat transfer from the dome to the base is ______________. kW (rounded off to the nearest integer).
