Question:

Consider two black coaxial parallel circular disks of equal diameter D that are spaced apart by a distance L. The top and bottom disks have uniform temperatures of 500°C and 520°C, respectively. Determine the radiation heat transfer coefficient h_radbetween the disks if they are spaced apart by L = D.

T2 = 500°C T = 520°C Ai!
