Radiation leaves a furnace of inside surface
Chapter 12, Problem 12.60(choose chapter or problem)
Radiation leaves a furnace of inside surface temperature1500 K through an aperture 20 mm in diameter. A por-tion of the radiation is intercepted by a detector that is1 m from the aperture, has a surface area of 10?5m2,and is oriented as shown.If the aperture is open, what is the rate at which radia-tion leaving the furnace is intercepted by the detector?If the aperture is covered with a diffuse, semitrans-parent material of spectral transmissivity ???0.8 for?2?m and ???0 for ??2?m, what is the rateat which radiation leaving the furnace is interceptedby the detector?
