Consider radiative heat transfer inside a cylinder with a radius R and length L (= R). The
two flat surfaces of the cylinder are maintained at 1000K, while the curved surface of the
cylinder is maintained at 300K. Both flat surfaces have an emissivity of 0.5, while the
curved surface is black. Calculate the net radiative heat flux on the curved surface.
Assume that the medium inside the cylinder is radiatively non-participating.
