A tubular heater with a black inner surface of uniform temperature T s = 1000 K irradiates

Question:

A tubular heater with a black inner surface of uniform temperature T_s = 1000 K irradiates a coaxial disk.

(a) Determine the radiant power from the heater which is incident on the disk, q_s?1. What is the irradiation on the disk, G₁?

(b) For disk diameters of Di = 25, 50, and 100 mm, plot q_s?1 and G₁ as a function of the separation distance L₁ for 0 L₁ 200 mm.
