Question:

A polished aluminum sheet is placed between the plates of Problem 14.12 as a radiation shield. The emissivity of the aluminum is 0.1. How much does the shield lower the flux to plate 2?

Prob. 14.12

Two large parallel plates are at temperatures T1 = 500 K and T2= 300 K. Their emissivities are ε1 = 0.85 and ε= 0.90. What is the radiant flux between the plates?
