Question

A spherical tank of diameter D 2 m that is filled with liquid nitrogen
at 100 K is kept in an evacuated cubic enclosure whose sides are 3
m long. The emissivities of the spherical tank and the enclosure are
10.1 and 2 0.8, respectively. If the temperature of the cubic
enclosure is measured to be 240 K, determine the net rate of
radiation heat transfer to the liquid nitrogen.​
