An electric arc considered as a black sphere of 5 mm diameter at a temperature of 5000 Celsius is situated 250 mm away from a metal dosk of 100 mm diameter. The disk is oriented at right angle to the normal to the arc and is open to radiation on both sides. Assuming that the heat exchange with the disk is entirely by radiation, estimate the temperature of the disk when the room temperature is 20 Celsius.
