A foundry is using a furnace to reheat billets. The furnace maintains a temperature of 1,400°C and is losing heat from a 0.3 m x 0.6 m opening for the billets to enter the furnace. If the ambient temperature is 27°C with an h = 10 W/m2-K, and treating the opening as a blackbody (emissivity of 1) determine the radiation heat loss in W.
