Consider a hot cylindrical surface and a disk oriented as shown in the figure. Both the cylindrical surface and the disk behave as blackbody. The cylinder has a diameter D and a length L of 0.2 m. The disk of diameter D = 0.2 m is placed coaxially with the cylinder at a distance of L = 0.2 m apart. The cylindrical surface and the disk are maintained at uniform temperatures of 1000 K and 300 K, respectively. Determine the rate of heat transfer by radiation from cylindrical surface to the disk.
