Question

Heat Transfer

(20) Radiation is emitted from a small opening (A 10 m2) of a furnace in which surface temperature is constant to be 2000K. The inner surface of the furnace is diffuse and gray (E-0.5). A portion of this radiation is intercepted by three detectors that are 0.5m from the aperture as shown below. The area of three detectors is the same as 10 m2 The area of the opening of the furnace and detectors can be considered as infinitesimally small, what is the rate of radiation intercepted by each detector?
